Series 2 of the hit crime drama Broadchurch was a bit of a stinker, so as filming begins on the third and final series the creators have brought in Sir Lenny Henry. Not the most exciting decision maybe, but, in-between the odd stay in a Premier Inn, old Lenny has become a well respected dramatic actor over the past few years. The final series will focus on a serious sexual assault, and look at the continuing repercussions on the lives of those involved in the original murder investigation of series 1. In other big news, Broadchurch writer Chris Chibnall will replace Steven Moffat as the head writer and executive producer of Doctor Who.
