Which actor plays Ant-Man in the MCU?

Paul Rudd plays Ant-Man, the superhero identity of Scott Lang, in the Marvel Cinematic Universe. Rudd first appears as Lang in Ant-Man (2015), directed by Peyton Reed, and returns in Captain America: Civil War, Ant-Man and the Wasp, Avengers: Endgame, and Ant-Man and the Wasp: Quantumania.

Scott Lang is a former electrical engineer and burglar who becomes involved with scientist Hank Pym. Pym gives him the original Ant-Man suit, which uses shrinking technology and allows the wearer to communicate with ants. Unlike many MCU heroes, Lang is not originally a military leader, billionaire, god, or trained assassin; his resourcefulness and loyalty to his daughter Cassie are central to his character.

The other options are connected to the Ant-Man films but do not play Ant-Man. Corey Stoll portrays villain Darren Cross, Evangeline Lilly plays Hope van Dyne—who later becomes the Wasp—and Michael Douglas plays the original Ant-Man, Hank Pym. Paul Rudd also co-wrote Ant-Man and the Wasp: Quantumania.
