Olivia Swann has built an increasingly recognizable career across television and film, moving from an early appearance in the British medical drama Doctors to major roles in DC’s Legends of Tomorrow, River Wild, and NCIS: Sydney. Although her screen filmography is still relatively focused Olivia Swann Movies and TV Shows, the roles she has taken on have allowed her to work across several genres, including science fiction, fantasy, action, crime drama, thriller, and adventure.
For many viewers, Swann first became familiar as Astra Logue in DC’s Legends of Tomorrow. She later took on a very different challenge as NCIS Special Agent Michelle Mackey in NCIS: Sydney, a role that placed her at the center of an international crime drama.
This guide covers Olivia Swann’s movies and TV shows, her major characters, her career timeline, and the projects that have helped shape her acting career.
Who Is Olivia Swann?
Olivia Swann is an English actress who was born in London and grew up in Birmingham. She trained at East 15 Acting School in London, where she developed her skills for stage and screen.
Before becoming widely known on television, Swann gained professional experience through theatre. One of her early stage roles was Mina Murray in a UK tour of Dracula. Her theatre background is useful context when looking at her later screen work because many of her television characters require a strong presence, emotional control, and the ability to move between dramatic and lighter scenes.
Her professional television career began with an appearance in the long-running BBC series Doctors in 2018. Her career then took a major step forward when she joined DC’s Legends of Tomorrow as Astra Logue.
The CW’s official biography notes that Swann trained at East 15 Acting School, appeared in Doctors, and also played the lead role in the UK tour of Dracula.
After several seasons with Legends of Tomorrow, Swann expanded into film with River Wild in 2023. That same year, she began another important chapter of her career as Michelle Mackey in NCIS: Sydney. Paramount describes her as the lead NCIS Special Agent in the series.

Olivia Swann TV Shows
Television has been the biggest part of Olivia Swann’s screen career so far. Her TV roles have taken her from a single appearance in a British medical drama to leading a multinational investigative team in Australia.
Doctors
Swann’s earliest credited television appearance came in the BBC medical drama Doctors in 2018.
She played Karinna Hailes in the episode “Scar Tissue.” The role was relatively small compared with the characters she would play later, but it marked an important beginning for her professional television career.
Doctors is a long-running British daytime drama known for its stories about medical professionals and the people who visit their practice. Appearing on an established television production gave Swann early experience working within the demands of episodic television.
Her role in Doctors is easy to overlook when focusing only on her best-known projects, but it belongs at the beginning of her screen timeline.
DC’s Legends of Tomorrow
For many viewers, DC’s Legends of Tomorrow is the project that put Olivia Swann on the map.
Swann played Astra Logue, a complicated character connected to the show’s supernatural and fantasy storylines. She first appeared as a guest character before becoming a much more important member of the series.
The CW’s official material describes Astra as a woman who was dragged to Hell after a failed exorcism and later grew into a powerful, complicated figure. Her story involves questions of power, trust, revenge, friendship, and redemption.
Astra was not a conventional superhero. That made the role particularly interesting for Swann because the character could be intimidating in one scene and vulnerable in another.
As the series developed, Astra’s relationship with John Constantine and the other Legends became increasingly important. She had her own ambitions and was often willing to make questionable decisions to achieve what she wanted.
The character eventually became a series regular, giving Swann much more room to develop Astra’s personality and relationships.
The CW’s official Legends of Tomorrow materials list Swann as Astra Logue and describe her as a former Queen of Hell who eventually becomes part of the Legends’ wider story.
Why Astra Logue Was an Important Role for Olivia Swann
Astra gave Swann the opportunity to play a character with a complicated emotional history rather than a simple hero or villain.
She had been shaped by trauma, anger, and years spent in Hell. At the same time, she wanted independence and control over her own life. Those conflicting qualities made Astra unpredictable.
The role also required Swann to work within the unusual tone of Legends of Tomorrow. The series regularly mixed science fiction, fantasy, comedy, historical adventures, and superhero storytelling.
That meant Astra could be involved in a serious emotional storyline one week and a much lighter adventure the next.
DC’s own coverage of the character highlights Astra’s struggle between her desire for power and her attempts to do the right thing while working alongside the Legends.
For Swann, the role was an important opportunity to establish herself as an actress who could handle action, fantasy, comedy, and emotional drama within the same series.
NCIS: Sydney
After Legends of Tomorrow, Olivia Swann moved into a very different type of television role.
She stars as Michelle Mackey in NCIS: Sydney, the international installment of the long-running NCIS franchise.
The series follows a multinational team made up of U.S. Naval Criminal Investigative Service agents and Australian Federal Police officers. Together, they investigate crimes connected to the U.S. Navy and the wider Indo-Pacific region.
Swann plays NCIS Special Agent Michelle Mackey, who leads the NCIS side of the team.
Her Australian counterpart is Sergeant Jim “JD” Dempsey, played by Todd Lasance. The two characters have different professional backgrounds and approaches to investigations, creating one of the central working relationships in the series.
Paramount’s official information identifies Swann as one of the show’s principal cast members and describes Michelle Mackey as an NCIS Special Agent.
Who Is Michelle Mackey?
Michelle Mackey is a confident and highly capable investigator. She is used to taking responsibility and making difficult decisions, which is important because she works in a high-pressure environment.
However, the character has more depth than her tough exterior initially suggests.
As NCIS: Sydney progresses, viewers learn more about Mackey’s personal history, relationships, and the experiences that have shaped her approach to leadership.
This makes the role quite different from Astra Logue.
Astra operates in a supernatural world where the rules can change from one adventure to another. Mackey, by contrast, works in a procedural crime drama where investigations, evidence, teamwork, and professional judgment are central to the story.
That contrast shows the range Swann has developed since joining Legends of Tomorrow.
NCIS: Sydney Season 3
NCIS: Sydney continued with its third season, giving Swann another substantial run as Michelle Mackey.
CBS lists Swann among the principal cast and identifies the series as having three seasons. The third season continued to follow Mackey and her team as they handled cases involving military personnel, international threats, and personal conflicts.
Season 3 also explored more of Mackey’s personal life. The storyline involving her son added another dimension to the character and allowed the series to explore the difference between Mackey’s professional confidence and her more vulnerable personal side.
By the third season, Mackey was no longer simply the tough leader introduced at the beginning of the show. Her relationships with the members of her team had developed, and her experiences had changed the way she approached both leadership and personal relationships.
This character development has helped make NCIS: Sydney one of the most important projects in Swann’s career.
Olivia Swann Movies
Although Olivia Swann has become better known through television, she has also appeared in film.
Her feature-film work includes River Wild, while her screen credits also include the short film Together, Alone.
River Wild
River Wild is one of Olivia Swann’s most notable movie appearances.
Released in 2023, the thriller stars Leighton Meester, Adam Brody, Taran Killam, and Olivia Swann. Swann plays Karissa.
The story centers on a group of friends who go on a whitewater rafting trip that gradually becomes much more dangerous than expected. As the situation develops, the characters have to deal with threats from both their surroundings and each other.
Swann’s role as Karissa gave her an opportunity to work in a feature-film environment after spending several years on television.
Paramount’s official biography for Swann specifically notes her appearance in River Wild opposite Leighton Meester and Adam Brody.
Her agency also lists River Wild in her professional credits and identifies her character as Karissa.
For people searching for Olivia Swann movies, River Wild is the most prominent feature film to start with.
Together, Alone
Together, Alone is a short film in which Swann plays May.
Unlike River Wild, this is a smaller-scale production, but it remains part of her screen work.
Short films can give actors opportunities to explore characters and storytelling formats that are different from mainstream television or feature films. In Swann’s case, it sits between her larger television projects and her later work in NCIS: Sydney.
Her professional agency lists Together, Alone as a 2022 screen credit with Swann in the role of May.
Olivia Swann’s Most Famous Roles
Two roles stand out most clearly when looking at Olivia Swann’s career: Astra Logue and Michelle Mackey.
Astra Logue
Astra is the role that introduced Swann to a large international television audience.
The character’s supernatural background, strong personality, and complicated relationship with the Legends gave Swann plenty of room to show different sides of her acting.
Astra’s journey from a character associated with Hell to someone trying to find her place among the Legends also provided a long-term character arc.
Michelle Mackey
Michelle Mackey represents another important stage in Swann’s career.
As the central NCIS agent in NCIS: Sydney, she carries much more responsibility within the story. The character is a team leader, investigator, and central figure in the show’s personal and professional storylines.
The move from Astra to Mackey also demonstrates Swann’s ability to transition between genres.
One role is rooted in the DC superhero and supernatural universe. The other is grounded in crime investigations and military-related cases.

What Is Olivia Swann Best Known For?
Olivia Swann is best known for two major television characters: Astra Logue in DC’s Legends of Tomorrow and Michelle Mackey in NCIS: Sydney.
Astra helped establish her internationally, particularly among fans of DC television. Michelle Mackey then gave her a leading role in a mainstream crime and action series.
The two characters are very different, which is one of the more interesting aspects of Swann’s career.
Astra is connected to supernatural mythology, magic, Hell, and time travel. Mackey works in a realistic investigative setting involving the NCIS and Australian Federal Police.
The change demonstrates that Swann’s career has not been limited to one genre.
What Makes Olivia Swann’s Roles Interesting?
One common feature of Swann’s major characters is that they are strong without being completely one-dimensional.
Astra is confident and sometimes aggressive, but her decisions are influenced by her past and her fear of losing control.
Mackey is similarly tough and decisive, but NCIS: Sydney gradually reveals the personal experiences behind her professional exterior.
This gives Swann opportunities to play characters who have both authority and vulnerability.
It is also interesting to compare how those qualities work in different genres.
In Legends of Tomorrow, her character’s conflicts can involve magic, supernatural forces, and time travel. In NCIS: Sydney, the conflicts are built around investigations, criminal cases, military threats, and relationships within the team.
