A recent report has stated that Nathan Fillion has been cast as Henry Pym and the announcement would be happening closer to Comic-Con, if not at it. According to our source, Henry Pym is not close to being cast yet. We did not get any confirmation that Henry would be in the film, although it is very likely, but our source has confidently told us that Nathan Fillion has not met with anybody at Marvel Studios regarding the film or any roles in the Marvel Universe.
Our source also filled us in on Kevin Pennington’s role and told us it is not likely anything would be announced until Comic-Con or after. The previous list of potential characters he could play, however, has been slashed down to three choices, including: Noh-Varr, Rick Jones and Clint Barton (not as Hawkeye yet). Our source did confirm he would be “working with Fury” and would likely have a future in the upcoming S.H.I.E.L.D. film.
UPDATE: You can find the report I was referencing about the Nathan Fillion rumor here.
UPDATE #2: Kevin just tweeted this morning that he will NOT be Clint Barton/Hawkeye in The Avengers. So we can cross that character off the list.
