During tonight's MTV Movie Awards, hosted by Jason Sudeikis, what celebs and surprises can we expect? Our friends at Moviefone have it covered:

Sure, we're all deeply invested in who wins a Golden Popcorn trophy for 'Best Kiss' (our bet's on Natalie Portman and Mila Kunis for their 'Black Swan' smooch). But we're also really amped to see new, exclusive 'Harry Potter,' 'Breaking Dawn' and 'Super 8' trailers.

And don't forget the parade of big names: This year, look for Kristen Stewart, Robert Pattinson, Taylor Lautner, Shia LaBeouf, Ryan Reynolds, Leighton Meester, Emma Stone, Blake Lively and Cameron Diaz, for starters.

After the jump, check out the list of movie clips -- and movie stars -- in store.
