'I think it would be a shame if Captain Jack wasn't involved in the 50th anniversary, because he was such a big figure and a big presence within the show itself and also within Torchwood,' he told MTV Geek.
Barrowman revealed he had discussed the matter with Smith and Doctor Who writer Steven Moffat and that they both thought it was 'a great idea'.
'It's not up to me, it's up to the executives, and it's also kind of up to the fans, because if they want it, all they have to do is get on those keyboards and start writing. You have been known to change things,' Barrowman added.
Steven Moffat wanted Barrowman's character to feature on the 2011 Doctor Who episode A Good Man Goes To War, however the actor was unable to return as he was filming Torchwood: Miracle Day in America.
