So far, all Edgar Wright has said about which version of Ant-Man actor Paul Rudd will be playing in 2015's Ant-Man from Marvel Studios is that Henry Pym will appear in the movie. That doesn't mean it's Rudd's character. That doesn't mean he's the main character. He's just... there.
Now, in a flickr post labeled only "Homework," Wright could simply be taking in any and all instances of Ant-Man in multimedia that he can. Sure, it could be that simple. But how deep could this tease also go?
The image is from Avengers: Earth's Mightiest Heroes season 2 episode 5, "To Steal an Ant-Man." The episode features Henry Pym, of course, but also introduces the second Ant-Man, Scott Lang, who steals the suit and decides to use it for his own gain. Could it be a hint to Rudd actually playing Lang in the film, stealing Pym's invention?
Interestingly, the episode also debuted the "Heroes for Hire," Luke Cage and Iron Fist, who will also make a live action debut in 2015, as part of Netflix's Marvel Studios deal for the "Defenders" series of TV series. For those that want to go extra deep, it could be a hint at a direct link between those TV series and Wright's film.
Of course, again, it could all just be that Wright is watching how Ant-Man has been portrayed outside of comics before. Maybe next he'll post a screenshot of Henry Pym as Yellowjacket in Marvel Ultimate Alliance 2, setting off an internet firestorm of Yellowjacket rumors for the film.
