Among a litany of other projects, Marvel Studios is hard at work on a third Ant-Man movie titled Ant-Man and the Wasp: Quantumania, set to hit theaters on February 17, 2023. The plot is being kept under wraps, but the title would suggest that the Quantum Realm will feature heavily. Maybe we’ll finally get to see the city inside that bubble.

More details about the story will be revealed in due time, as will further casting announcements. For the time being, these stars are confirmed to appear in the Ant-Man threequel.

Paul Rudd

This one should come as no surprise, but Paul Rudd will appear in Ant-Man and the Wasp: Quantumania, playing the role of Ant-Man. This will mark Rudd’s fifth time playing the bitesize hero on the big screen after his previous two solo movies, Captain America: Civil War, and Avengers: Endgame. During the long wait for Quantumania’s 2023 release date, fans can catch Rudd in Jason Reitman’s upcoming Ghostbusters reboot alongside Finn Wolfhard, Carrie Coon, and the surviving members of the original cast.

In addition to starring as the title character, Rudd received a writing credit on the first two Ant-Man films. On the first one, Rudd was tasked with rewriting Edgar Wright and Joe Cornish’s original draft with the help of Anchorman director Adam McKay. However, Rudd is stepping down from writing duties for the next one. The script for Quantumania is credited solely to Rick and Morty writer Jeff Loveness.

Evangeline Lilly

Evangeline Lilly will reprise her role as Hope van Dyne, the daughter of the original Ant-Man and the Wasp, in Quantumania. After being relegated to a love interest role in the first Ant-Man movie, Hope finally got to enjoy some superheroics in the flying Wasp suit in the 2018 sequel. The Wasp’s solo adventures have so far been tagged onto Ant-Man’s, but she could get her own movie in the future or play a key role in an A-Force movie.

Having played the crucial role of Kate on ABC’s Lost for six seasons, Lilly is no stranger to densely packed shooting schedules and multi-year commitments to a role. If anything, Marvel’s commitments might seem lax and easygoing after pumping out 20-plus hours of material a year about an island.

Michael Douglas

Michael Douglas is confirmed to reprise his role as Hank Pym in Quantumania. Hank is, of course, the genius behind the Ant-Man technology and was the first person to don the suit and fight crime with it. Like the other Ant-Man movies, Quantumania might feature a couple of flashbacks showing a de-aged Hank in his heyday.

Since Marvel has traditionally killed off its mentor figures to motivate its heroes and Hank has recently redeemed his years of terrible parenting, some fans are expecting him to be the MCU’s next major character death. But Douglas is such a great foil for Rudd that this seems like it would be a waste.

Michelle Pfeiffer

Janet Van Dyne in Ant-Man and the Wasp

Throughout the first Ant-Man movie, Hank was presented as a widower because his wife Janet got lost in the Quantum Realm years earlier. However, when Scott went to the Quantum Realm and lived to tell the tale in the final battle, it gave Hank hope that Janet could still be saved. This set up a delightfully emotional story arc for the sequel, as Hank dedicates all his time to figuring out how to enter the Quantum Realm and safely leave again.

This paved the way for Michelle Pfeiffer’s introduction as Janet. Pfeiffer is confirmed to return in the threequel, which could dig deeper into the psychological effect of being trapped in the Quantum Realm for 30 years. Since the sky is the limit with de-aging technology, flashbacks in Quantumania could show us more of the original Wasp in action.

Kathryn Newton

Kathryn Newton as Abigail in Big Little Lies

Although Emma Fuhrmann played Scott Lang’s daughter Cassie after the time jump in Avengers: Endgame, the part will be played by Kathryn Newton in Quantumania. The reasoning for the recasting is that Fuhrmann was cast by the Russos and wasn’t Ant-Man director Peyton Reed’s top choice, so she’s been replaced. It’s a shame, because Fuhrmann did a great job in Endgame and shared heartwarming chemistry with Rudd in their brief scenes together.

The casting of a bigger name (Newton isn’t Angelina Jolie or anything, but she’s been in Freaky, Detective Pikachu, and Big Little Lies), paired with Endgame’s time jump, suggests that Cassie will finally take on her superhero mantle as Stature and possibly lead the MCU’s Young Avengers in Quantumania.

Jonathan Majors

He Who Remains raises his hands in Loki

There were plenty of surprises in the first season of Loki, but arguably the biggest was the introduction of Jonathan Majors as “He Who Remains.” Majors had been announced to be playing Kang the Conqueror in Ant-Man and the Wasp: Quantumania months before Loki aired.

While the character who appeared in the Loki finale wasn’t identified on-screen as Kang and was killed by Sylvie within minutes, the character in the Ant-Man threequel will be the real deal, a variant of He Who Remains who actually goes by the name Kang. According to Loki head writer Michael Waldron, he’s being set up as “the next big cross-movie villain.”
