It’s one thing to find movies where woman are dominant (as well as men), another to find ones where usual roles are completely reversed and men are objectified, but here are some suggestions and you can decide whether they’re what you’re looking for:
Recently, Pacific Rim. While there is only one main woman character, she is the protagonist and hero. While it may seem initially that the male character is the lead, as soon as he meets her he is completely in awe of her and spends the rest of the movie worshipping at her feet basically, and she gets to see him topless while she is never sexualised herself. So. Yeah. It’s also a really fun movie.
Apart from that, agree with Alien (spoiler: all the dudes die), Terminator (sort of based around a dude though), and the Wizard of Oz (the wizard is kind of just used for his apparent powers while the little girl and witches run the show and it turns out he doesn’t even have powers and the girls do all the work anyhow so that’s pretty cool).
Black Widow, while being the only female in the team, has a pretty dominant role in The Avengers, and I must say, Cap’s booty is definitely objectified, as are Thor’s arms.
A couple of others I can think of are Little Women (while the men aren’t objectified, they are more portrayed as influences on the girls lives rather than the other way around), Legally Blonde and The Help.
