" Michael J. Fox has signed on to a four-episode arc on Rescue Me. Starting with the season premiere this spring, he'll play Janet's wheelchair-assisted new boyfriend.

" Marcia Gay Harden will face off with Glenn Close on Damages as an attorney for a shadowy, high-powered corporation. As previously announced, Timothy Olyphant and William Hurt, Close's Big Chill cohort, will be series regulars this season. "It's part of our molecules," Close said of her and Hurt's shared experience on the iconic boomer flick. And! Ted Danson will return for an unspecified number of episodes as Arthur Frobisher. Medical update: Producer Daniel Zelman says Arthur's "not terribly healthy at the moment, but he is alive."

" Drea De Matteo (Christufuh!), who appears in the pilot for FX's new biker drama Sons of Anarchy, has already signed on for two additional episodes.

" The network has green-lit an amazing 39 more episodes of sleeper sitcom It's Always Sunny in Philadelphia. That's in addition to the 13 that are already in production now and the 32 that have already aired.

" Look for 13 episodes of a comedy called Testees (two e's, people!) from Kenny Hotz, creator of Kenny and Spenny and a former South Park writer. Its protagonists make their living as medical test subjects, hence the suggestive series title. - Mickey O'Connor
