If and when BBC decides to order a fourth season of "Torchwood," executive producer Russell T. Davies says he'll be ready to go.

The man responsible for bringing "Doctor Who" back to television and making it a smash success said he expects good things to come from so-called "mini-season" of "Torchwood" that comprises of the show's third season. The cast, which currently includes John Barrowman as Capt. Jack Harkness, Eve Myles as Gwen Cooper and Gareth David-Lloyd as Ianto Jones, had to say good-bye to two other cast members last season, Burn Gorman and Naoko Mori, whose characters of Owen Harper and Toshiko Sato were killed off.

The special comes the same time as the show's parent, "Doctor Who," also took an abbreviated season, leaving overall Whoniverse audiences asking for more. A lot more.

The latest miniseries, "Children of the Earth," is set to premiere on BBC America in the United States July 20, around the same exact time it will air on BBC. It will run over a five-day week, and then be available as a DVD release a week later.

Davies said it will depend how the show does this season on whether or not BBC will order more, but "Torchwood" has been a hit with British and American audiences alike, actually picking up BBCA's strongest ratings for a scripted drama.

The latest season welcomes Peter Bennet to the production team that already has Davies and Julie Gardner, and all five episodes are being directed by Euros Lyn. Davies wrote the first and fifth episodes with the middle episodes written by James Moran and John Fay.

Davies said he has the fourth season mapped out already, and likely could go another six years beyond that. While it would be typical parlance to say that depends on whether or not the remaining actors will stick around, it seems the Who universe has a way of continuing on, even when there has been significant cast changes. So time will tell whether "Torchwood" has that same type of staying power as "Doctor Who."
