Sarah Jessica Parker. Ashton Kutcher. Halle Berry. Hilary Swank. Zac Efron. Robert De Niro. Jessica Biel. Katherine Heigl. Jon Bon Jovi. Sofia Vergara. Michelle Pfeiffer. What do all of these celebs have in common? They're all jammed into 'New Year's Eve,' the latest movie to stuff as many stars as humanly possible onto the screen.

This isn't the first time Hollywood has corralled a hefty helping of stars into one flick. It's a pretty safe strategy when it comes to luring people to the theaters; after all, there are plenty of folks out there to go to the movies to see, well, stars. And 'New Year's Eve' seems to have someone for everyone: Heigl and Bon Jovi for the rom-com fans, SJP for the moms, Lea Michele for the Gleeks and Efron for the teenage girls.

Unfortunately, too many stars can often come at the expense of a decent plot. Watching 'New Year's Eve,' for instance, feels a lot like watching clips from eight different movies all spliced together ... with the occasional overlap, of course. It also seems as though casting stars took priority over casting actors who were appropriate for the roles they were cast in. It's really tough to buy Lea Michele and Ashton Kutcher as an item -- no matter how cozy they've been acting together on the red carpets lately to promote this flick. 'New Year's Eve' features one other incredibly unbelievable pairing, but to tell you who the unlikely duo is would be giving too much away. As much as I hate unrealistic casting, I hate jerks who spoiler movies even more.


Sometimes, however, having plenty of stars does work. Case in point: 'Ocean's Eleven.' The ensemble cast included Hollywood heavyweights like Brad Pitt, George Clooney, Matt Damon and Julia Roberts. But thanks to their great chemistry and a strong script, the star overload didn't detract from the movie. Every character had an important role to play in the script's overarching plotline: the heist. It didn't feel like any of the characters had extraneous scenes just to fit in more screen time for one of the megastars.

When the stars align and the celeb-studded movies work, it can be a beautiful thing. When it doesn't work, things can get pretty confusing with too many sub-plots going on to justify jamming all of those big names onto the poster. We've compiled a gallery highlighting some of the most memorable flicks that are bursting with stars in recent memory -- the good, the bad and the downright ugly.
