Piecing together the mighty Marvel Cinematic Universe is no easy task, and by necessity if nothing else, Marvel Studios has scheduled films through 2020. In those films releasing between now and then, Marvel will pit their heroes against each other in Captain America: Civil War, introduce new heroes with Doctor Strange, Captain Marvel, and Inhumans, as well as re-introduce a few in Spider-Man and Black Panther.
On top of all that, several of Marvel's heroes are getting their second (or in some cases third) shot at the spotlight in Phase 3. Among them are Ant-Man and The Wasp with the Ant-Man sequel aptly named, Ant-Man and The Wasp. Stars Paul Rudd and Evangeline Lilly are already set to return, along with Peyton Reed back as director. Ant-Man co-writer Adam McKay may also return, but there's no official word on that yet. (The film won't release until 2018, after all).
However, we can report that Marvel is looking to bring back another of Ant-Man's stars - the original Ant-Man, Hank Pym a.k.a. Michael Douglas. While talking with Collider, Douglas confirmed he has been contacted by Marvel in regards to Ant-Man and The Wasp:
"I just got a call recently – they want to negotiate for a sequel and I thought “That’s great!” Hopefully, I won’t have to carry quite as much expositional dialogue as the first one but I had a wonderful time doing it. Just a great, great time. The cast was fantastic. Paul, Evangeline, Michael Pena – I’m sure he’ll be back. If they can scrape Corey Stoll off the wall, I’m sure they’ll want him too – he’s such a good villain. And Peyton too. It was a lovely experience, so you know, I welcome it. I chuckle about being involved with a movie that already has a release date in 2018. Ya know, it’s hard to conceive of that, but it’s all good, all the way around, it’s all good."
We're hoping Michael Pena returns, too, as his character was a certified scene-stealer and helped elevate Ant-Man from being just another humdrum hero origin tale. As for Corey Stoll, he likely won't be returning since his villain, Yellowjacket was squashed into nothingness. Then again, never say never, these are comic book movies and no one stays dead for long (Red Skull, anyone?).
Bringing Douglas back for Ant-Man and The Wasp is a real no-brainer. During the mid-credits scene for Ant-Man, Pym revealed The Wasp suit he created for Hope, so surely Pym will be needed for any development, training, maintenance, etc. But hopefully these scenes aren't too stuffed with "expositional dialogue." Plus, the rapport between Douglas, Rudd and Lilly was a big part of Ant-Man's appeal, and a sequel where Hope gets to do her own superhero-ing along side Scott Lang really needs Pym around to ground the trio.
