Because he is made of win. John is, of course, also in Doctor Who. He plays Captain Jack Harkness, pansexual ex-Time Agent who travels with Rose and the Ninth Doctor for five episodes and Martha and the Tenth for three. He's got his own spin-off show, Torchwood, which is an adult-Doctor Who based primarily in Cardiff. I think he's the only character that no one hates at all. He's also Scottish, but lived in America for quite awhile (long enough to be considered Scottish-American). He can do both accents. He is also very much into theatre of a different kind than David. Instead of Shakespeare, he does things like Grease and Phatom of the Opera. Yes, he's into musical theatre. And he's brilliant at it. Seriously, go youtube him.
He did a cameo in the movie "The Producers" as the leading Nazi singing "Springtime for Hitler". He's blond and blue eyed in that, but for real he's just got browns.
He was on the celebrity ice-skating show, "Dancing on Ice" which he was also..very good at...He was in Shark Attack 3: Megladon, where he said the most ridiculous ad-libbed line which for some reasons unknown, wasn't edited out. You can youtube that too. It's ridiculous.
He's known for being a "force of nature, a lovely and lively man" "a bundle of fun" "upbeat" etc.
He's currently living in Cardiff with his civil partner, Scott.
That's John Barrowman...
