Tom Hiddleston as Loki. I'd never seen Tom until Thor and from the first scene with him I was hooked. I tracked down his earlier film roles from British television, Suburban Shootout, Wallander, The Deep Blue Sea, War Horse and Midnight in Paris, the Hollow Crown, Avengers, the Dark World, Only Lovers left Alive and his most recent Coriolanus. So talented. My favorite actor!!
