Ant-Man was a charming, relatively low-stakes entry in the Marvel Cinematic Universe that was buoyed along by a witty, charismatic cast. But according to two separate reports, two major actors aren’t sure if they’ll be returning for the sequel, Ant-Man and the Wasp, which is supposed to start production this summer.

The title characters, played by Paul Rudd and Evangeline Lilly, are safe, of course, but Ant-Man’s best friend and ex-wife might not be. Michael Peña, who played the affable, fast-talking ex-con Luis, told Collider on Monday that he hadn’t gotten a call from Marvel.

“I don’t know if I’m gonna get the phone call,” he said. “Who knows?”

“I don’t think they have to call you at all,” explained Peña, who signed a multi-picture deal with Marvel. “They could just say that he’s free to go and he can do any movie that he wants at this period of time. I don’t really know what’s going on with that. There’s always possibilities that you’re not going to be in that movie. You just prepare yourself for that.”

In August, The Hollywood Reporter wrote that he was set to reappear in the sequel, but Peña’s recent comments to Collider seem to suggest that wasn’t a sure thing.

On Tuesday, Vulture reported that Judy Greer, who played Ant-Man’s ex-wife, Maggie, was in a similar boat. “They haven’t asked, so I’m willing to campaign for it,” Greer explained. “I’d love to. Working with Paul [Rudd] and Bobby [Cannavale] was amazing, and then [director] Peyton Reed is amazing.”

Even though Peña and Greer haven’t gotten any calls yet, they and their characters could still reappear in the sequel. With contracts like theirs, the studio doesn’t need to give them a ton of notice. Still, it’s interesting that two major players from the first film are seemingly up in the air with filming about to start in July — especially because Peña stole every scene he was in.

Ant-Man and the Wasp will crawl into theaters on July 6, 2018.
