Peter Capaldi on playing a “sympathetic serial killer” and Doctor Who parallels [Video]

Season 1 saw Gideon, a man who is reborn every time he dies and who has devoted his life to prevent terrible tragedies from happening, locked in a cell.

But at the end of the season, he escapes and, this time around, he’s unleashed onto the world as he and Jessica Raine’s Lucy Chambers form an uneasy alliance to attempt to stop a devastating incident.

“I think I do empathise with him,” Capaldi tells RadioTimes.com in an exclusive interview. “What’s driving him is a desire to keep people, ironically, safe – and he’s trapped.

“He has knowledge that traps him to a position where he either does nothing or he acts upon this knowledge. The path that he’s chosen is a dangerous one.”

If season 1 was a supernatural mystery, season 2 is an all-out thriller, with Gideon and Lucy racing against the clock and grappling with their newfound alliance.
