Hey, Firefly/Charmed slash-fic writers: Alyssa Milano will play a love interest for Nathan Fillion's Richard Castle on Castle in a 2010 episode. You're welcome.

Hey, Firefly/Angel/Lost slash-fic writers: Gina Torres will play an associate of Ian Smolderhottie's Damon Salvatore in the 10th episode of The Vampire Diaries. Her character, Bree, is a witch who helps Damon get into a tomb. (This news is also for Cleopatra 2525/Smallville 'shippers.)

We're pretty sure no one has ever mashed up Arrested Development and Doctor Who, but if they did, the news that Jeffrey Tambor will co-star with David Tennant on the latter's new series Rex Is Not Your Lawyer would surely please them. Tennant's character suffers from panic attacks, and coaches his clients to represent themselves; Tambor will play Rex's psychiatrist, who has his own anxiety problems and also dates Rex's mom. Worst psychiatrist ever.

Larry Charles, bearded writer and producer of Seinfeld, The Tick and Entourage, has teamed up with Terminator Salvation helmer McG to create a TV show about sci-fi geeks who decide to film their own episodes when their favorite TV show is cancelled.

Hello, nurse-- er, doctor! Belle, the ex-prostitute author of the blog that inspired Secret Diary of a Call Girl, has finally revealed herself to be Dr. Brooke Magnanti, a specialist in developmental neurotoxicology and cancer epidemiology.

This week is Observer week, since Thursday's Fringe episode features more than one of the mysterious bald dudes, and there will be Observe-alikes out and about giving people spicy gifts. You can find out where they're going to be on Facebook, and you can see the first three minutes of the episode here.

Oh, and the Hawkman costume from Smallville's upcoming Justice Society two-parter has been revealed, and it... looks a lot like the one in the comics. It's certainly the opposite end of the Smallville costume spectrum from the Wonder Twins' plaid shirt and black tutu last episode, but it may be a bit... much. Now I'm frightened to see what Stargirl looks like.
