Tom Hiddleston first appeared in Thor as the blond, gargantuan god’s pallid, brooding, maniacal half-brother Loki. He then reappeared in The Avengers with a greasy black mane that he sometimes chose to keep hidden beneath his headgear of choice: a helmet featuring two gargantuan horns. Hiddles even made a surprise appearance at the San Diego Comic-Con as Loki, and judging from the bloodcurdling screams, managed to have the entire female audience under his evil spell. He’ll be reprising his role as the evil mastermind from Asgard in Thor: The Dark World, and showed up at the Berlin premiere looking refined and dapper in a suit. Now just unabashedly stare into those green eyes — or if you prefer him darker, catch him at the tail end of the trailer.
