Morning Brew – Friday, January 6: “Grey’s” gives Calzona an alternate timeline, Tina Fey caused Alec Baldwin’s WWF meltdown

Good morning, Brewbies! Trish Bendix is off at the wild, wild world of the Television Critics Association winter press tour, so I’ll be covering Brew through next week. If you want to help shape our TCA coverage — which, frankly, is some of the best in the business — leave a comment or vote in the poll on yesterday’s Brew!

You know how Grey’s Anatomy is planning an alternate universe episode for lthis year’s finale? (By the way, Shonda Rhimes, you should have consulted Hart Hanson to see how that worked out for him on Bones). Spoiler king Michael Ausiello has offered up some interesting tidbits about what we can expect, including what the space-time continuum rift will mean for Calzona:

TVLINE | Do Callie and Arizona figure into the episode at all?
Shonda Rhimes: They do. And that is the best part. If Meredith is bright and shiny, Arizona remains unchanged, but a lot about Callie’s universe is very different. If Meredith was never dark and twisty, she never would’ve slept with George, who never would’ve fallen down the stairs and dislocated his shoulder, and he never would’ve met Callie.

Rhimes also said in the second half of this season “everything blows up to holy hell.” So, you know, just a standard Grey’s back half.

AfterElton.com Hot 100 winner Darren Criss took over for Dan Radcliffe this week at How To Succeed at Business Without Really Trying. The Glee star made his Broadway debut to mixed reviews, but Jane Lynch was on-hand to show her full support.

Last night on The Late Show With David Letterman, Tina Fey stopped by to hype the new season of 30 Rock. She also revealed that she is the one who deserves the blame for Alec Baldwin‘s recent Word With Friends meltdown.

When I heard that news story, the thing I was most upset about was, like, seven months ago I was all, “Hey, Alec. There’s this fun game called Words With Friends. It’s a lot like Scrabble, but it’s a little different. You should get it!” And he was like, “Eh, I don’t know.” And so I didn’t think he’d ever got it — because he’s never invited me to play with him!

Oh, how I wish the dude actors on 30 Rock would stop acting like jackholes so Tina could spend her publicity time telling stories about her daughter Alice instead of cleaning up their messes.

Thought you couldn’t love Kristen Bell any more than you already do? Think again! While doing the press rounds for her new show House of Lies, she told Moviefone that she did the full Katniss Everdeen for Halloween: “All my friends dressed as the characters [from the Hunger Games] and I dressed as Katniss. I was head-to-toe in spandex with a fire cape and carried a bow and arrow.” She also said she’s stumping for the roll of Johanna in Mockingjay and Catching Fire: “I am trying to stay on top of it and not age too rapidly so that I can still be cast!”

I hope she’s prepared to fight Bridget McManus for that role!

I don’t know about you, but I am already camped out in front of the TV waiting for the American premiere of Downton Abbey‘s second season on PBS this Sunday night. My roommate is inexplicably Team Edith, and I am fully Team Mary, so I expect it’s going to be dicey around our house for the next couple of months. One thing we can agree on, though, is that Maggie Smith is Dowager Countess of our hearts! While you’re waiting — or gloating because you’re in the UK and have already seen series two — why not take the Downton Abbey personality quiz to see which character you most resemble.

Yeah, that’s right: I’m a Lady Sybil Crawley. Probably that means I’m going to marry myself.

I hope you guys have a wonderful weekend. Get some rest. TCA and winter TV both kick into high gear next week!
