Rashida would be great, but I could also see Mary Elizabeth Winstead or Anna Kendrick as Wasp. Or Olivia Wilde, maybe Rachel McAdams, or if you want a bigger name for Janet how about Mila Kunis? There are plenty who can play Janet
Winstead, sure. Kendrick? possibly but i'd be disappointed (and it might seem creepy). Olivia Wilde seems out of Rudd's league. McAdams would probably look strange in a superhero costume. and i just don't like Kunis. cute or not, she still has Meg's voice.
educated speculating. making a movie about ant-man without jan is like making a batman movie without alfred or a superman movie without lois lane, a dr. strange movie without the ancient one or a thor movie without mjölnir.Is it confirmed that Janet Pym will be in the movie, or are we just speculating?
I can't remember having seen any film with Paul Rudd. Let's just hope he's good, now that he got the role over other candidates like Jamie Bell.
Nathan Fillion said that he couldn't take the role because of his commitment to the Castle series. Isn't that just a lame excuse? The Ant-Man film has been in pre-production for many years. If Fillion really wanted to play the superhero, he could have talked to Marvel studios lots of times, and together they could have made a plan for him to be available at the right moment. But Fillion doesn't want to be Ant-Man. It's a shame that he can't admit it though.
Fillion turned down Guardians of the galaxy and Green Lantern too. And GL is Warner, not Marvel.It might be the other way 'round, and Marvel isn't interested in casting Fillion as a superhero. In fact, that seems much more likely than the idea that he has turned down roles or could just walk in and ask Marvel to cast him.

Either no studio want him in their superhero films, or he actually doesn't want to play any superhero at all.
One of the roles I first noticed Paul Rudd in was as Paris in Baz Luhrmann's Romeo + JulietI'm not concerned about Rudd's ability, as dude was doing theatre for years before he hit the Judd Aptaow scene. It's just that Hollywood pays him to be the smart ass guy in every movie as opposed to anything else. I did see My Idiot Brother the other night and he was award worthy in that.

Nathan Fillion was never in contention for the role his name was just about because some Fillion/Whedon/Marvel fans wanted him in the role. Fillion himself has said for a number of years that he wasn't interested in the role and doesn't like the character. The constant questioning of him about the Ant-Man role got to the point that he was actually a bit annoyed kept asking him.
In addition to that, Wright has tweeted that he likes Fillion but doesn't understand why people want him for Ant-Man. Most fans obviously either ignored this or saw it as a red herring at the time.
Alan Tudyk as well was another actor who said he isn't interested but fans kept hassling him about the role. Simon Pegg as well has stated numerous times over the years he won't be playing Ant-Man.
I think once an actor says they aren't interested fans should really drop it and move on.
Paul Rudd is one of the most enthusiastic actors about a role that Marvel has ever had according Feige. Better to have a actor who is happy to have the part than one who doesn't. No one wants another Weaving Red Skull situation.
