As Captain America: The Winter Soldier enters theaters in April, Marvel Studios will begin principal photography on Ant-Man, the first new solo character film from the production house since 2011. With a fast approaching start date, director Edgar Wright is filling out the cast, with funnyman Paul Rudd taking the lead and Marvel announcing this week that two-time Oscar winner Michael Douglas (Wall Street) will be joining him.

These are the only two names officially attached to the project by Disney and Marvel thus far, but reports yesterday put Michael Pena (Gangster Squad, End of Watch) in talks for a key role as well, potentially as a villain from the past. Now we’ve learned that Clifton Collins Jr. (Pacific Rim) has also signed on for Ant-Man.

When Pena’s name made the trades yesterday, other names including Clifton Collins Jr. and Javier Bardem popped as well, as potential persons of interest for Marvel, all seemingly for the same role. According to Latino-Review, Collins Jr. has already signed on to join the cast and is the only name – alongside Douglas and Rudd – to be officially aboard the project.

Clifton Collins Jr., a likable and experienced character actor, will likely take on a supporting role and is a fitting addition to the Edgar Wright project. He’s a pal of Wright in real life, had a memorable cameo in Scott Pilgrim vs the World, and is no stranger to sci-fi flicks and big budget blockbusters. He had an important role in last summer’s Pacific Rim for Warner Bros. and before that, in Paramount’s Star Trek quasi-reboot which him sharing the screen as the the right-hand to Eric Bana’s villainous Nero. He can next be seen in Transcendence, one of Screen Rant’s most anticipated movies of 2014.

We don’t have any details on Collins Jr.’s role but if yesterday’s rumors about the potential plot of Ant-Man involving scenes in the ’60s with Michael Pena’s character playing a communist leader that young Hank Pym is spying against, it wouldn’t be surprising if Collins Jr. showed up in those scenes as well given that THR described the pair – and what Marvel is looking for – as “tough Latinos.” It’s also possible he could be playing a second rumored villain who surfaces in the modern era who Scott Lang (Rudd) must face off against.
