Jessica Biel stopped by tonight's Late Show to chat with David Letterman and promote New Year's Eve, rom-com king Garry Marshall's star-studded regurgitation of 2010's inexplicably successful Valentine's Day. At one point, Letterman read Biel a list of about 15 of her A-list co-star to see how many of them she'd actually filmed with—any guesses?

Here's a new full-length trailer for the upcoming ensemble romcom New Year's Eve, director Garry Marshall's second attempt, after the catastrophe that was Valentine's Day, to tap into Love Actually's sprawling charm. Yuck.

Here's the trailer for New Year's Eve, an upcoming ensemble film from rom-com king Garry Marshall. The movie follows several couples (and some poor singles) around New York City on the last day of the year—where they all become intertwined in some way, naturally—and looks to be a carbon copy of Marshall's last movie, Valentine's Day, except in a different city and on a different holiday.

No one really knows, so one director, and possibly one actress, are endeavoring to find out. Also today: NBC orders two dubious sounding pilots, Matthew Weiner has a casting change for his first movie, and trouble in New Zealand.

It just might happen. Also today: a Three Musketeers movie rounds out its cast, good news for Conchords fans, amazing news for Twilight fans, and gut-busting brain-imploding news for Justin Bieber fans.

Today we offer a new pair of videos as an addendum to our recent, authoritative list of Dos and Donts for Making the Perfect Celebrity PSA. First up: Absolutely DO coax Ron Howard and Henry Winkler into whatever outlandish pro-Obama Happy Days reprise they can stand, such as the one after the jump that premiered today at Funny or Die. And if Andy Griffith agrees to join Howard for a bewigged ride all the way back to Mayberry, all the better. However: DO NOT, under any circumstances, enlist Rhea Perlman, Valerie Harper and/or Garry Freaking Marshall as your elder voice of reason. Especially Marshall! This election is just too close — and Georgia Rule far too recent — to risk some new, William Ayers-like smear campaign this late in the game.Click to view
