Tom Hiddleston didn't originally want to play Loki in the Thor franchise. He auditioned to play Thor himself. He shared his audition with Jimmy Kimmel. (if you play the clip, it will go directly to the part about the audition.)
He was working with Kenneth Branagh onstage, and when he heard that he would be directing Thor, he burst into Branagh's dressing room pretending to wield a giant hammer. Still, Tom attempts to hide his thirst, claiming that he thought he was auditioning for "just a movie... an interesting part in an interesting movie."
Which is more cringeworthy?
