The Ausiello Files just posted an exclusive story on John Barrowman and his most famous character, Captain Jack Harkness of Doctor Who and Torchwood fame.
Barrowman claims that:
I hope wherever [the franchise] goes that the show stays the same.
The last thing I would want would be for Jack to become this heterosexual, straight hero. He’s an omnisexual guy. He likes men, women, aliens, whatever. I think we should continue going down that route.
As for the US version of the show, the actor has no information yet other than Fox has commissionned a script from Russell T. Davies and that he would reprise his role as Captain Jack.
