Wait come back! I know what youre thinking. Either who the hell is Squirrel Girl? or who in their right mind would make a film about Squirrel Girl? Both points are valid, but hear me out. The cinematic Marvel Universe has always had a sense of humor and with the news that Paul Rudd has been cast as Ant-Man, its clear that Phase 3 will have laughs aplenty. Who better to star in a follow up comedy than a super hero who can climb trees and talk to squirrels in their own language? Squirrel Girl will have to be played for laughs of course but dont underestimate her. In the comics, shes defeated both Doctor Doom and Wolverinesingle handedly. That bitch got game! Should Be Played By: Jena Malone Its tempting to cast a comedian in a role like this but I think that Jena Malone has both the talent and the sass to carry off such a ridiculous character, playing her completely straight.
