Pretty much every actor in Hollywood shows up in 'New Year's Eve,' director Garry Marshall's follow-up of sorts to the equally star-studded 'Valentine's Day.' The ensemble of characters deals with babies, lost loves, resolutions and everything in between on, you guessed it, New Year's Eve.

Among the celebs on board to ring in the new year are (deep breath) Zac Efron, Hilary Swank, Halle Berry, Robert DeNiro, Michelle Pfeiffer, Lea Michele, Sarah Jessica Parker, Katherine Heigl, Ashton Kutcher and Jon Bon Jovi.

The film hits theaters on December 9 -- check out the trailer below:
