Quick -- think of your favorite Hollywood movie star. Chances are that he or she is in the upcoming "New Year's Eve."

The latest trailer for the all-star film piles on the cutesy romance and passing moments of comedy pretty thick, and features the film's plethora of stars, including (deep breath): Halle Berry, Ashton Kutcher, Katherin Heigl, Zac Efron, Robert De Niro, Ludacris, Hilary Swank, Michelle Pfeiffer, Sarah Jessica Parker, Jon Bon Jovi, and others.

They all play denizens of New York City who are entangled in various romantic couplings, just like the players in the last film from Garry Marshall, "Valentine's Day."

And, of course, Ryan Seacrest plays Ryan Seacrest.

The film opens nationwide December 9.
