While Idris Elba will soon be cancelling the apocalypse in Guillermo del Toro’s Pacific Rim, his cop drama Luther has just kicked off its third series on the UK’s BBC One. The first of four hourlong episodes topped Tuesday night in the ratings with 5M viewers for a 21.7% share. But according to overnight data, it was the lowest series debut in the show’s history and 600,000 viewers off from the last Luther episode which aired in 2011. Still, the return of the BBC/BBC America co-production has been well-reviewed by local critics. Stateside, the third season runs on BBC America on consecutive nights from September 3-6. Sienna Guillory features as Luther’s new love interest in this go-around. Returning cast members include Warren Brown, Nikki Amuka-Bird, Dermot Crowley and Michael Smiley. Here’s a trailer for the new episodes:
