<Li> David Dastmalchian as Kurt: A member of Lang's crew . Dastmalchian, who is American, worked with actress Isidora Goreshter to learn how to speak in his character's Russian accent . On his character, Dastmalchian said that he "had this idea that Kurt was born and raised in a town even further out than Siberia and he was just an amazing computer wizard who fell in with the wrong people . But he was obsessed with two things: Saturday Night Fever and Elvis Presley, hence the polyester shirts unbuttoned too far and the hair in that pompadour ." </Li> <Li> Michael Douglas as Hank Pym: A former S.H.I.E.L.D. agent, entomologist, and physicist who became the original Ant - Man in 1963 after discovering the subatomic particles that make the transformation possible . He later mentors Lang to take over the role . Douglas compared his decision to join a superhero film to his role in Behind the Candelabra saying, "Sometimes--like (when) they didn't see you for Liberace--you've got to shake them up a little bit and have some fun ." Describing Pym, Douglas said, "He's sort of a Northern California, formal guy . He's lost control of his company . He lives in sort of a time warp . He was always a bit of a tinkerer . He's got a lab, plus a lot of other stuff, in his basement that we find out about . He's certainly bitter about what happened with his company and deeply scared of what the future might hold--because he himself, after having gotten small so many times, it's difficult . He looks and tries to find a guy that he can work with and has the right characteristics, which is (Scott)." Douglas indicated that he would not be wearing the Ant - Man suit . </Li> <P> Additionally, John Slattery and Hayley Atwell reprise their roles as Howard Stark and Peggy Carter, respectively, from previous MCU media . Slattery stated that his involvement in Ant - Man was "not that much more" than his participation in Iron Man 2, while Atwell described her appearance as being "more of a cameo". Abby Ryder Fortson portrays Cassie, the daughter of Lang and Maggie; Gregg Turkington appears as Dale, the manager of a Baskin - Robbins store; and Martin Donovan plays Mitchell Carson, a former member of S.H.I.E.L.D. who works for Hydra and looks to purchase the Yellowjacket technology . YouTuber Anna Akana portrays a writer in Luis' story at the end of the film . Garrett Morris, who portrayed Ant - Man in a Saturday Night Live sketch, appears as a taxi driver . Ant - Man co-creator Stan Lee makes a cameo appearance in the film as a bartender . Chris Evans and Sebastian Stan make uncredited appearances during the post-credits scene as Steve Rogers / Captain America and Bucky Barnes / Winter Soldier, respectively . Hayley Lovitt makes a nonspeaking cameo as Janet van Dyne / Wasp . Tom Kenny provides the voice of a toy rabbit that Scott gives to Cassie . </P> <P> Development of an Ant - Man film began as early as the late 1980s, when Ant - Man co-creator Stan Lee pitched the idea to New World Pictures, Marvel Comics' parent company at the time . However, Walt Disney Pictures was developing a film based on a similar concept, Honey, I Shrunk the Kids, and although Ant - Man went into development, nothing came to fruition . </P>
