Do they have to do every movie(avengers/marvel)?
If all goes according to plan The Avengers film is scheduled for release July 2011 w/ Captain America the same year but released in May.

As far as the other characters you mentioned I believe they're doing an Antman film...don't ask me why, and I think it's Scott Lang not Hank Pym as the character who's playing Antman.

No mention of a Shield film...as of yet..but if they do make one I hope it's classic Nick Fury, not Ultimate..but I don't think that will happen.

Scarlet Witch and The Vision are not what you'd consider strong enough characters to warrant their own film...but the same could be said for Antman yet they're giving him one...go figure.



This is the time to produce these characters for film, look at the success of Iron Man, Hulk and The Dark Knight. If the studios take their time and get the right people behind in making these films... it's a natural progression and every comic fans dream to see these guys on the big screen.Do they have to do every movie(avengers/marvel)?
no
