'30 Rock'
(9:30PM, NBC)
Her career may be thriving, but so far, love has eluded Liz Lemon. Luckily for her, she's getting three episodes to close the deal with her new neighbor – the handsome and newly single Dr. Drew Baird, played by 'Mad Men' star Jon Hamm.

The hapless-in-love is gonna need all three episodes, too, as, like usual, she doesn't exactly make a great first impression on the good doctor.

Meanwhile, Jack's got his own romantic woes, as he tries to convince Elisa's (Salma Hayek) grandmother that he's a good catch. Too bad granny can't stop thinking about how much the GE honcho reminds her of the villain on her favorite Spanish soap opera.

'Life on Mars'
(10PM, ABC) series premiere
Imagine life before cell phones, the Internet and 'CSI'-type forensics ... that's where detective Sam Tyler finds himself after he's hit by a car in modern-day New York City.

Tyler awakens in 1973 NYC, with a different boss (Harvey Keitel), new cop cohorts (including 'The Sopranos' Michael Imperioli) and no idea why he's ended up back in time, though there are striking similarities between the bad guy he was pursuing in 2008 and the one he's investigating in 1973.

Is Sam actually in a coma? Is he dead, and 1973 is his afterlife? All questions that will be answered, assuming network execs let him live long enough to make it back to the future.

Twice a year, TV critics from across the country gather in Los Angeles for the Television Critics' Association press tour.

For two weeks the press gets the chance to chat with the actors and writers from every network and cable channel -- and showered with useless freebies (an oven mitt promoting 'Coolio's Rules'!) -- all to better understand the season's new shows.

Here are the best boob tube tidbits we gathered at the latest TCAs.
