Shaun Dingwall, who played Rose's father Pete Tyler in the first series this spring, apparently told several people at a recent photo signing that he might be in negotiations to return to the show for the second series, at least in a cameo appearance. There is currently no word on whether this is happening or which episode it would be, although there are rumors that it could be the final episode of the season.

John Barrowman is confirmed by DWM 360 to not be returning for the second series at all.

According to several reports based on an original comment in the Daily Star, Chris Evans, the former husband of Billie Piper, may be in the next season. "Doctor Who producers are reportedly trying to convince Chris Evans to make a guest appearance in the next series of the hit BBC One sci-fi show. The radio DJ would star as the Devil in an episode called The Satan Pit, when the show returns for a second series next year, the Daily Star claims. Evans' estranged wife Billie Piper already stars as Doctor Who's sidekick Rose Tyler in the series but, as they remain on good terms, the paper claims that his appearance as the Devil wouldn't be a hellish experience for the pair. An unnamed source told the Daily Star: 'We've already got some great celebrities lined up for the next series, but having Chris Evans would be the icing on the cake. Having him as Satan would be a hoot and we're sure he'd relish the role. And we know Billie would find it a giggle.'" Also reported at DeHavilland, ITN, Digital Spy.

Also, there are rumors that Anthony Stewart Head, who according to the latest issue of Doctor Who Magazine is playing Mr. Finch in episode three, "School Reunion," may not only be the head master of the school... but the Master. So says the Daily Star: "The super-villain, who was first played by the late Roger Delgado in the 1970s, will return in the next series. And insiders predict he will be played by Buffy The Vampire Slayer star Anthony Head, who was once tipped to play Doctor Who himself. The handsome star, 49, a regular in comedy smash Little Britain as the Prime Minister, was recently recruited to the Who cast by executive producer Russell T Davies. But nobody at the BBC will talk in detail about who he will be playing. Last night a series insider said: 'We can't say anything, other than confirm that Anthony Head is going to feature in an episode called School Reunion, in which he'll play the Headmaster.'" We're reliably reassured these are only rumors, though, and not based on truth, especially since the Daily Star article quotes "internet fan forums" (and we all know which internet fan forums they pay attention to...)

Finally... yes, we know Torchwood, which we reported the other day as being the potential word Russell T Davies referred to in his DWM production notes as being season two's "Bad Wolf", is an anagram for Doctor Who. As reported, the BBC registered a torchwood web address, so we may be onto something here...
