Nikki Finke's Deadline Hollywood, which broke the news that Chris Hemsworth had nabbed the title role in Kenneth Branagh's Thor, reports today that British actor Tom Hiddleston will play Thor's nemesis, Loki.
Hiddleston, unknown to American audiences, is an award-winning Royal Academy of Dramatic Arts graduate and played Winston Churchill's son in HBO's The Gathering Storm. He also starred in Ivanov opposite Branagh on the London stage and in the BBC miniseries Wallander.
Marvel Studios won't confirm the news, but Hiddleston had been considered as a possible Thor. Thor is slated for release on May 20, 2011.
