It's hard to tell that more "Torchwood" could be coming to fans anytime soon, especially with how busy John Barrowman's dance card has been as of late.

The actor, best known for his role as Capt. Jack Harkness both in that series and its parent series, "Doctor Who," says that despite his upcoming work in the new The CW series "Arrow," there could still be more "Torchwood" in his future.

"'Torchwood' is very popular, so I would personally love it to come back," Barrowman recently told Digital Spy. The delay, of course, is coming from series creator Russell T. Davies, who is currently back in England tending to his sick partner. Andrew Smith, Davies' longtime boyfriend, underwent surgery for brain cancer late last year, and is now recovering in England.

When Smith is feeling better, Barrowman is hoping to see some sort of return for "Torchwood" -- but how it will return? That's a big question.

"It will probably come back again, but under another guise," he said. "It might come back as another mini-series, or another full [season], or a movie even, so who knows?"

Barrowman is lining up some American television work, including "Arrow," but has had to turn down some offers because of his schedule. But he's busy even away from the television set. With Davies' blessing, Barrowman co-wrote a "Torchwood" novel "Exodus Code" that is being released in October.

BBC teamed up with the American cable channel Starz last year to release "Miracle Day," and the channel said it would be interested in ordering more -- when Davies is up for it.

"It's a character that I love and it's a show that I love," Barrowman said. "I'm not a suit who doesn't get into this world. I go around to all the conventions and there's a huge audience out there for it, and they want more."
