Whovians know the actor best for his roles in Doctor Who, and the Doctor Who spinoff Torchwood.
Jack Harkness is a relatively minor character in the Doctor Who universe, appearing in only 12 episodes over 5 years.
After a break this year, Doctor Who will be returning to our screens in 2017 for season 10 — and it sounds like Barrowman would like for Harkness to make a reappearance.
The long-running British sci-fi series introduced us to Barrowman as the charming, roguish time-traveler Jack Harkness, before he went on to star in the spin-off.
