THR reports that Anthony Hopkins is in negotiations to play Odin in Kenneth Branagh's adaptation of Thor. This contradicts earlier reports that Branagh-regular Brian Blessed was cast in that role.
Odin is the ruler of Asgard and father to both Thor (Chris Hemsworth) and Loki (Tom Hiddleston). In Thor, the Norse god of thunder finds himself cast out of Asgard and banished to Earth after his reckless actions re-ignite an ancient war. There he will learn how to become a hero when Earth is attacked by the dark forces of Asgard.
Hopkins can be seen in Woody Allen's upcoming You Will Meet a Tall Dark Stranger in the fall of 2010 and in The Wolfman on February 12, 2010 — that is, unless the release date changes yet again.
