#5. When Kenneth Branagh found out he’d be directing Thor (2011), he was performing in a production of an Anton Chekhov play. Branagh’s co-star in the play, Tom Hiddleston, wanted the role of Thor so bad that he approached Branagh wielding an empty water jug to simulate Thor’s hammer Mjolnir. The role of Thor went to a beefier dude (Chris Hemsworth), but Hiddleston nabbed the role of Loki.
