"New Years Eve" (PG-13)

Hilary Swank is responsible for coordinating the ball drop in Times Square, and she panics when there are last minute problems with its propulsion mechanism. Plus her opening act's backup singer, Lea Michele, is stuck in an elevator with Ashton Kutcher. It's directed by Garry Marshall, who also directed "Valentine's Day". Just like its predecessor, this romantic comedy has a huge ensemble cast which also includes Ludacris, Jon Bon Jovi, Zac Efron, Jessica Biel, Halle Berry, Katherine Heigl, Sofia Vergara, Robert De Niro, Michelle Pfeiffer, Sarah Jessica Parker, Abigail Breslin, Josh Duhamel, and "SNL's" Seth Meyers. Joey McIntyre from New Kids on the Block also makes a cameo appearance, along with Common, Alyssa Milano, Jim Belushi, and Ryan Seacrest as himself.
(You may remember that Ashton Kutcher and Jessica Biel were also in "Valentine's Day", but they played entirely different characters. That one was based in L.A. "New Year's Eve" obviously showcases New York City.)

"The Sitter" (R) (Trailer) (Red Band Trailer)
Jonah Hill plays a lazy college student who takes a job babysitting three kids. When his girlfriend lures him out of the house with the promise of sex, he takes the kids with him, and they eventually end up being chased around town by two drug dealers. (That sounds suspiciously like a remake of the 1987 comedy "Adventures in Babysitting". You can watch Elizabeth Shue sing "Babysitting Blues", which essentially recaps the entire plot of that movie, here.) There's a phone number for Jonah Hill's character on a flyer for the movie, and a lot of people have called to leave him voice messages.
