Former Doctor Who David Tennant has joined the cast of the U.S. revamp of his hit British drama Broadchurch. The Scottish actor will play a character similar to troubled police detective Alex Harvey, who he portrayed in the original Broadchurch, but this time he'll adopt an American accent, according to TV Guide magazine. The U.S. version of the series is expected to shoot in January (14) and air during the 2014-2015 TV season. The acclaimed original drama focused on the investigation of the mysterious death of a young boy in a small English coastal town. Broadchurch became the U.K.'s most-watched new drama of 2013.
