Yes, not exactly an "A-List" superhero, but he was a member of The Avengers.
The main guy behind the movies mentioned above is Edgar Wright, but according to him while Ant-Man will be funny, it won't be the same sort of humor seen in "Shaun" or "Fuzz." Here is his response when asked about the tone of the film:
"I don't want it to be a superhero spoof, because superhero spoofs and man-in-tights spoofs have absolutely been done to [expletive] death — after 'The Incredibles', which is sort of the last word on superhero parody. So it's going to be something different. It's going to be funny, but in a different way other than just, 'Hey, he's small!' [laughs] When it was first pitched to me, somebody said, 'It's Honey, I Shrunk the Superhero.' And I said, "I would do everything except that film." [laughs]
There will be no other "Avengers" in the film, either... the film will be just about the title character.
I'm not sure how they're going to balance the comic book roots of the character while making this one funny, considering the history of the Scott Lang version of Ant-Man: Imprisoned burglar, wife divorces him and he has a daughter that is deathly ill. I guess if anyone can pull it off, though, it's these guys.
