Stargate SG-1‘s Ben Browder is headed to the Old West for a rendezvous with another science fiction legend.
Browder guest stars in “A Town Called Mercy,” this week’s brand new episode of Doctor Who. He plays a cowboy named Isaac, who lives in the dusty town that is under siege by a relentless cyborg. When the Doctor, Amy, and Rory arrive, the Doctor is conscripted to be the town’s reluctant sheriff.
The episode is penned by Toby Whithouse, creator of the original U.K. version of Being Human.
Doctor Who stars Matt Smith, Karen Gillan, and Arthur Darvill, and airs Saturday, September 15 at 9/8c on BBC America and Canada’s SPACE, and at 7:35 p.m. on BBC1 in the U.K. Check out more photos at Digital Spy, and watch the trailer below!
