Which actress played Lucilla, the sister of Commodus, in Gladiator?

Connie Nielsen played Lucilla, the sister of Commodus, in Ridley Scott's Gladiator. Lucilla is also the former lover of Maximus, the Roman general played by Russell Crowe, and she becomes an important figure in the struggle against her brother's rule.

In the 2000 film, Joaquin Phoenix portrays Commodus as a jealous and power-hungry heir who murders his father, Emperor Marcus Aurelius, and seizes the throne. Lucilla must navigate the danger posed by Commodus while trying to protect her son Lucius and support opposition to the new emperor. Nielsen's performance gives the character both political intelligence and personal vulnerability.

Nielsen is a Danish actress whose other notable roles include Queen Hippolyta in the DC Extended Universe. She later reprised Lucilla in Gladiator II, released in 2024. The historical Lucilla was a real Roman imperial figure, but the film's family relationships, romance, and political events are heavily fictionalized for dramatic effect.
