Barrowman's 'Torchwood' sidekick named

Eve Myles will play the sidekick to John Barrowman's Captain Jack in upcoming Doctor Who spinoff Torchwood.

Wales-born Myles, who guested in the first series of Doctor Who, will play the part of Gwen Cooper, one of a team of renegade investigators who scavenge alien technology to solve crimes.

"I'm thrilled to be playing Gwen," said Myles. "It's such a compliment to have been chosen for the part. I'm also looking forward to working with John. It'll be the perfect opportunity for both of us to show everyone what we've got."

The thirteen episode series is being penned by Doctor Who writer Russell T Davies for an "adult" audience. The show will premiere on BBC Three later in the year and will have a repeat window on BBC One. Filming is expected to begin in the Summer.
