Oh, squee and a half–it’s Mary McDonnell on The Closer tonight (and for at least a few episodes beyond)! You may recall Ms. McDonnell from her Emmy-winning–OR IT HAD BETTER BE–role as President Laura Roslin on Battlestar Galactica, in which she rocked the airlock hard. She also recently appeared as a surgeon with Asperger’s Disorder on Grey’s Anatomy. She had a multi-ep arc on both ER and E/R, as well as roles on Touched by an Angel and High Society. And that’s not even counting her Oscar-nominated turns in Dances with Wolves and Passion Fish. I’d have loved her forever even without Roslin, just for being Donnie Darko’s mom. Now she’ll take on Chief Johnson as a hard-nosed Internal Affairs investigator. Put ’em out the airlock, Captain Raydor! Tonight on TNT at 9pm Eastern and Pacific.
