6. A New Hulk Movie
Given that Mark Ruffalo's turn as the "enormous green rage monster" garnered such love from critics and fans alike, surely he deserves his own feature? Edward Norton's The Incredible Hulk is technically considered canon, so a Ruffalo solo venture would be a sequel. The good news is that we wouldn't have to sit through a third re-telling of the origin story. The bad news is that Hulk tends to struggle as the star of the show. The character was wonderful when offset by amazing actors/characters like Tom Hiddleston's Loki and Robert Downey Jr.'s Iron Man, but hasn't yet had the solo film to rival those in the Iron Man, Captain America or Thor series (at least in the box office terms - he did, however, beat out Wolverine). With a strong director at the helm and a movie that showcases Ruffalo's complex Dr. Banner, a new Hulk installment could really work. As far as plot is concerned, they could do some wonderful stuff with a hybrid of the "Pardoned" and "Regression" story arcs. Watching Banner struggle to gain and maintain control over the savage inside could make for a seriously compelling watch.
