Casting Couch: Paging Kari Matchett to the "ER"

Veteran drama ER, returning this fall for what is possibly its very last outing, has landed yet another doctor.

Kari Matchett, late of 24 (in a role termed by one Televisionary reader as "Slutty Blonde Girl"), Invasion, Shark, and TNT's short-lived medical drama Heartland, has been cast on NBC's ER.

It's hardly surprising that Matchett will play a doctor, a role a role not unfamiliar to this actress, who has played a member of the medical profession twice in the last two seasons. (She also played a nurse a few years back on Canadian series Plague City.) On ER, she'll play Skye Wexler, the new attending in the County General Hospital emergency room.

Matchett, who played the traitorous Lisa Miller last season on 24, will have some company from that real-time thriller as Reiko Aylesworth (a.k.a. Michelle Dessler) joins the cast of the long-running medical drama on October 25th.

What I'll Be Watching

8:30 pm: 30 Rock.

On season finale of 30 Rock ("Hiatus"), Liz and Floyd try to work out the kinks in their long-distance relationship, Jack's impending wedding brings his mother (guest star Elaine Stritch) to New York, and Kenneth searches for the missing Tracy.

9 pm: The Office.

On tonight's repeat episode of The Office ("Beach Games"), Michael is up for a promotion at Dunder-Mifflin Corporate and decides to hold a day of Survivor-inspired challenges at the beach as a means of choosing his successor, leading a jealous Pam to watch Jim and Karen from the sidelines.

10-11 pm: It's Always Sunny in Philadelphia on FX.

It's the season premiere of FX's hilariously subversive comedy It's Always Sunny in Philadelphia, here with two back-to-back episodes. On the first ("The Gang Finds a Dumpster Baby"), Dennis, Dee, and Mac find a baby in a Dumpster and Dee and Mac decide to raise him and use him to raise some cash as a baby actor. One problem: white babies aren't in style right now. On the second ("The Gang Gets Invincible"), Mac, Dennis, and Dee try out for the Philadelphia Eagles but really try to outdo one another, only to run afoul of the dreaded McPoyle family. Watch it; you'll thank me in the morning.

10 pm: Tim Gunn's Guide to Style on Bravo.

See the style maven make it work on his own fashion series, where he and supermodel Veronica Webb take on one hapless fashion victim and make them over into a sartorial superstar. On tonight's episode, Tim and Veronica deal with a woman who recently lost a lot of weight.
