Doctor Who star John Barrowman has revealed which Doctor he believes is the best ever.

The Scottish-American actor joined Doctor Who as Captain Jack Harkness in 2005 and appeared alongside both Christopher Eccleston and David Tennant in the show, before starring in spin-off series Torchwood.

Chatting to The Big Issue as part of their regular ‘Letter To My Younger Self’ feature, he said: “I think David Tennant was the best ever Doctor, no one can hold a candle to him.”

He added: “I used to watch Doctor Who with Jon Pertwee, then Tom Baker, every Sunday night on the local Chicago TV station. I failed every Monday morning spelling test because of that show.”

Looking back on his time playing Captain Jack, Barrowman commented: “It would blow my 16-year-old’s brain (even more) if I told him: you’re going to be one of the most iconic characters in Doctor Who for the next two or three generations.”

He went on to recall how he first won the part: “If I could go back and relive one moment in my life, I’d go to the moment I got the job as Captain Jack [above] in Doctor Who. I’d gone to audition for this role of a rogue, matinee idol type, in front of the execs Russell T Davies and Phil Collinson. I walked into the meeting with my motorbike leathers on, and I took my helmet off and shook out my hair.

“Later on Russell told me: ‘When you walked into that room and took your helmet off, we both fucking wet ourselves. You were so handsome, and your physique with those leathers on… We thought we were watching some kind of porn movie. Neither of us could remember much about what you said after that.’

“Later on I was walking through the West End and I got a phone call; they said, hands down, without a doubt, everyone agrees John Barrowman is definitively Captain Jack. I started screaming in the middle of Covent Garden and then I ran and did a Jimmy Cagney backflip off a wall. That was the day my life changed forever.”

Barrowman has just signed a new deal that will see his Arrow character appear in spin-offs The Flash and Legends of Tomorrow. He has played bad guy Malcolm Merlyn (aka the Dark Archer) in Arrow since 2012 and became a regular cast member in Season 3.
