Tom Hiddleston loves playing the \"bad guy\". The British actor recently reprised his Loki alter-ego in the film Avengers Assemble with the likes of Scarlett Johansson and Robert Downey Jr. He told Glamour magazine: \"The devil plays all the best tunes. Playing a superhero bad guy is just pure escapism as an actor, there\'s just so much freedom. \"The bad guy is always completely free of moral censure... It was enormous fun.\" Tom, 31, recently worked with acclaimed directors Woody Allen on Midnight In Paris and Steven Spielberg in War Horse. \"You have to try very, very hard not to completely lose your mind and become a crazy fan boy,\" he said. \"And also now be scared in their company because what they want is your contribution as an actor, and if you\'re nervous, that\'s the last thing you\'re going to give them.\"
