A two hour pilot has already been filmed for 'The Dresden Files' which will lead to an 11 episode series for the Sci-Fi Channel. The show will be about a Chicago private detective with wizardly powers named Harry Dresden who is consulted when crimes have an otherworldly connection. It's being described as "supernatural noir" and will debut in January.
Being a contemporary show, 'The Dresden Files' sounds like a natural for an appearance by any of the alumni from 'Buffy The Vampire Slayer' or from 'Charmed'. Since he flew to Chicago in the finale of his own show, even Dr. Frasier Crane might be believable in a more light-hearted episode of the show, and thus expand the number of his appearances in Toobworld.
And Chicago was the setting for the classic 'Kolchak: The Night Stalker' series as well as for a short-lived but fun show called 'Special Unit 2'. As "SP2" focused their attentions on the same kind of supernatural doings that Harry Dresden will probably be investigating, at least a reference or two to their covert operations might be in order (although I'd love to see Danny Woodburn return in his role as a thieving gnome).
