Here’s a quick look at some of the casting announcements made recently:

In Treatment: It remains to be seen whether Amy Ryan will return to The Office. But until then, she’ll be In Treatment. The Academy Award nominee will be seated as Dr. Paul Weston’s therapist, not his patient.

Dexter: SPOILER ALERT! We should expect to see two blondes in the upcoming season of Dexter. Julie Benz (a.k.a. Dexter’s Rita) will make an appearance in the very first episode. (I’m guessing we’ll see what happened to her?) Meanwhile, Julia Stiles (The Bourne Identity) will reportedly play a major part in Season 5. Her storyline is being kept under wraps.

Desperate Housewives: Vanessa Williams’ run on ABC didn’t end with Ugly Betty. The actress will now join the cast of Desperate Housewives as the latest resident of Wisteria Lane. No details about her character have been disclosed.

Parks and Recreation: Will Forte recently cameoed a cross dresser obsessed with Jenna Maloney on 30 Rock, but now he’s got a new obsession: Twilight. The MacGruber star will guest on an episode of the NBC comedy as a Pawnee resident whose love of the vampire series gets in the way of a Leslie Knope project.

White Collar: USA Network has collared Diane Farr for an appearance in Season 2. The Rescue Me alum will be featured as a waitress that seeks an interested Mozzie (Willie Garson) for help. The series will resume on July 13.
