I guess after news broke yesterday of Michael Douglas being cast as Hank Pym for Ant-man and nobody had predicted it, everyone started pumping their Ant-man sources for information because suddenly it's a big issue.
Even though Marvel denies any talks are going on (don't they always?), The Wrap, THR, Collider and several other major outlets are reporting that Michael Pena is in negotiations for a role in the movie. The part is unknown, but Marvel has been scouting for a "tough Latino" who is ready for a very physical role.
This Is Infamous says that they know what the role is for however, saying Pena will play Castillo.
While it took awhile to piece together the timeline, our understanding is that Castillo will be the film’s villain in the beginning, which takes place in the 1960s. It is here that we’ll get our introduction to Ant-Man – the Hank Pym version – which Marvel readers will get from the character’s work as a spy fighting against Communism. From there, Ant-Man will move into the modern era, with an aging Pym, recently filled by Michael Douglas, and the beginning of the Scott Lang story arc, which will eventually get Scott Lang in as Ant-Man. Lang will encounter this second villain along the way, who will serve as his primary villain, but what we’re hearing is that Peña will wind up playing a larger role as the film develops, much more than just the opening to establish Ant-Man.
Variety piles on with another casting tidbit for a female part in the movie, naming Rashida Jones and Bryce Dallas Howard as two actresses up for the part:
The female lead of this film is the daughter of the second male lead. In light of the last day’s news, that pretty clearly marks her out as the offspring of Hank Pym.
Could we be looking at new take on Janet Van Dyne (The Wasp) with this part? Although Collider is disputing that Jones or Howard are up for any parts in the movie.
Latino Review is also reporting that actor Clifton Collins Jr. has come on board for the movie, but they don't know for what role.
