Katherine Heigl and Gerard Butler are getting 'Ugly.' Brad Pitt is hunting Nazis.
Vince Vaughn is having fun with 'Couples.'
Matt Damon is looking plumper than ever.
And those crazy 'Potter' kids must be up to something.
Behold this week's five hottest new movie trailers and clips:
5. 'The Ugly Truth' -- Red-Band Clip
"Mr. Perfect" Gerard Butler finally informs Katherine Heigl what her breasts are really saying to the world ...
4. 'Inglourious Basterds' -- Trailer #2
Finally, a full-length look at Quentin Tarantino's Nazi slaughter fest, featuring a cameo appearance by Hitler.
3. 'Couples Retreat' -- First Trailer
Another 'Swingers' reunion! Of course, now Vince Vaughn and Jon Favreau are married (not to each other), and forced to spend a drab weekend at "Disneyland for adults."
2. 'The Informant' -- First Trailer
Not only does Matt Damon nail it as a mustached moron, but we've got a rare Scott Bakula sighting here, not to mention Tony Hale (Buster from 'Arrested Development').
1. 'Harry Potter and the Half-Blood Prince' -- Exclusive Clip
Harry's got a dangerous book of potions and his fellow Hogwarters want to know whose it is (hint: it's the Half-Blood Prince's!).
