Speaking at the Wizard World Chicago Comic Con Barrowman mentioned Doctor Who's current lead writer and executive producer Steven Moffat as the reason Torchwood would not be back, to which Moffat has clarified that he is not one of those obstacles:
You may be aware that John Barrowman has been saying, publicly, that I've been blocking a new series of Torchwood. To be very clear - I haven't blocked it; I wouldn't block it; I wouldn't even be ABLE to block it. I didn't even know a revival had been mooted till I read about it on the Internet. As John perfectly well knows, it's not my show and I could no more prevent it happening that he could cancel Sherlock. I am bewildered, and a little cross, even to be included in this conversation. For the record, I really liked the show (especially the third series) and would be very happy to see more - monsters and mayhem, why not? But the fact is, it has nothing to do with me. Please pass this on to the anxious and the angry - I've had enough hate mail now.
