Biografía

Although he predominantly speaks with an American accent, he says he always speaks with his parents in his natural Scottish Accent.

Owns a Dalek from the season one finale of 'Doctor Who' and has it placed near his front door.

Was a big fan of ''Doctor Who'' growing up.

He auditioned to play the Ninth Doctor.

According to his autobiography, when the part of Will in Will y Grace (1998) came down to him and Eric McCormack, the producers decided to go with Eric because, as they told John, he (John) was "too straight-acting." John, meanwhile, is openly gay, but they went with a straight actor for the role.

I was gobsmacked by that. I was absolutely gobsmacked. All these things that are happening. I just sit back and . . . I can't believe it but I love it. I'm totally enjoying it. Because I'm a fan, a sci-fi fan, they have made a young boy's dreams come true. (after being told that his role in Torchwood (2006) had propelled him to "instantaneous National Treasure status")

There's a lot of me in Captain Jack and there's a lot of Captain Jack in me. And there is no pun intended. (on his role as Captain Jack Harkness on Torchwood (2006))

I'm not the sort that likes to go out and get hammered, I'm not the Hotel Babylon (2006) and I let that go years ago now that I am older and wiser.

Remember that I have a family. Remember that I have teenage nieces and nephews--and younger--who do surf the Internet for stuff about their uncle. And I would appreciate if you don't make up rumors and things about me. If you want the facts, go to my Web site. I'm truthful. I'm honest about the way I talk. If you want the truth, come to me. (on what he thinks of what is written about him on the Internet, which he refuses to read)

In the back of his mind, Captain Jack really wants to die because he's lived a long, long time. (on his character's immortality in Torchwood (2006))
