Get ready, fans of Marvel’sAnt-Manfranchise, as a third installment is on its way.Ant-Man and the Wasp: Quantumaniawill be released in theaters on August 11, 2025. The 31st entry in the Marvel Cinematic Universe will reunite Paul Rudd’s titular Ant-Man alongside Evangeline Lilly’s Wasp.
While we know that Rudd and Lilly are returning, we do not yet have much concrete plot information about the story. The list of confirmed cast members may give us some idea about what to expect and who we might see from previous films and Marvel properties. In addition to the returning players, there are also some new faces joining the cast and rumors and speculation on big-name stars such as Bill Murray.
With that in mind, let’s look at everything we know about the cast of Marvel’sAnt-Man and the Wasp: Quantumania. In addition to Rudd and Lilly, who is returning from the previous two films? Are any major players not coming back for the third installment? What new cast members will be joining, and who is rumored to appear?
Quantumania: Who Is Returning?
As mentioned above,Paul Ruddis back as the titular Scott Lang/Ant-Man, withEvangeline Lillyas Hope Van Dyne/The Wasp, both returning from the first two films. In addition to theAnt-Manfranchise, Rudd portrayed the character inCaptain America: Civil WarandAvengers: Endgame. Lilly’s Wasp also made an appearance inEndgame.
Michael Douglas is back inQuantumaniaas original Ant-Man Hank Pym, with his most recent appearance also coming inAvengers: Endgame.Michelle Pfeiffer’s Janet Van Dyne will be returningas well. Janet is the mother of Hope, wife of Hank, and the original Wasp, who first appeared in 2018’sAnt-Man and the Waspand laterAvengers: Endgame.
Fans will recall that Scott Lang went into the Quantum Realm at the end ofAnt-Man and the Wasp,where he spent five years, emerging inEndgame. While the rest of the world moved ahead five years, Lang only experienced a passage of five hours (sort of like how Paul Rudd himself has seemingly not aged in over 20 years). When Lang emerged, he had to adapt to everything lost to him over the last five years. This was not touched on extensively inEndgame, so Rudd’s arc as Lang inQuantumaniawill likely revolve around working through that trauma.
As of this writing, Rudd, Lilly, Douglas, and Pfeiffer are the only confirmed cast members from the previous twoAnt-Manfilms returning.
Quantumania: Who Has Not Been Confirmed?
It is still early, with nearly a year to go until the release, so we could see more previous cast members return to reprise their roles from earlier installments. Notably, some major cast members from the earlier films have not yet been confirmed to appear. Michael Pena portrayed Luis, a member of Lang’s crew and his former cellmate. Bobby Cannavale starred as Jim Paxton, the current husband of Lang’s ex-wife Maggie, played by a now similarly absent Judy Greer.
Members of Lang’s team, such as Dave, played by rapper T.I., and Kurt, played by David Dastmalchian, have also not been confirmed as appearing. There are no headline stars from any other MCU films lined up as of now, but as they often appear in cameos or post-credit scenes, the filmmakers may just be keeping any potential appearances under wraps.

Again, we need to stress that we are still months out from the release ofQuantumania, and return appearances from any of these stars could still be announced. However, given how central they were to the first two films, it seems strange that they were not previously reported with the other returning players.
Quantumania: Who Are the New Players?
For two of the three new players with confirmed roles, their characters are not new to the MCU. Kathryn Newton is joining the cast ofQuantumaniaas Cassie Lang, the daughter of Scott Lang. While this is the first time Newton is playing the character, Cassie is no stranger to the MCU. She first appeared in the originalAnt-Manfilm, portrayed by young actress Abby Ryder Fortson. Fortson would reprise the role inAnt-Man and the Wasp. When Cassie appeared inEndgame, the character was aged five years to account for Lang’s time in the Quantum Realm. Here, the role was played by Emma Fuhrmann.
Quantumaniawill also seeJonathan Majors appear as Kang the Conqueror. This is Majors’ first appearance as the character in anAnt-Manfilm. Majors previously appeared as He Who Remains, an alternate timeline version of the same character in the first season of the Disney+ seriesLoki.

Finally, in one of the most talked-about castings, Bill Murray is joining the MCU. We do not yet know his role, only that it is a villain, withMurray himself describing the role as a “bad guy.”Since Majors’ Kang is confirmed as the primary villain, Murray’s character may be a lesser villain. Maybe he will assist Kang, or perhaps he will act on his own against Lang. Playing a villain is somewhat unfamiliar territory for Murray, best known for his comedic roles in classic films likeCaddyshackandGhostbusters.
