Holy crawfish, PopWatchers! According to the NY Post, Liza Minnelli has just signed on to guest-star on an episode of Law & Order: Criminal Intent that gets its ripped-from-the-headlines inspiration from the JonBenet Ramsey murder case, and subsequent creepy John Karr confession. (Thanks to TV Tattle for the heads up.) Liza will play the victim’s mother, and if she’s half as good as she was as Buster’s dizzy paramour on Arrested Development, this will mark the first ever tryst between my DVR and the Criminal Intent flavor of L&O.

Couple this news with Chevy Chase playing a Mel Gibson-esque movie star on original L&O later this season, and it looks like Dick Wolf’s franchise is becoming a career revitalizer for underemployed actors. I’d like to see American Pie graduates Tara Reid and Natasha Lyonne as pop-star sisters who try to evade questioning after their hard-driving manager/father gets arrested for the murder of an aggressive photographer. Or how about Destiny’s Child star Michelle Williams as a temperamental supermodel whose assistant is hurled off a 40th-floor balcony during a crowded fashion-week party? What say you, readers? Who else could benefit from a Law & Order guest role, and how would you cast ‘em?
