Horror + Comedy = All kinds of awesome films! Best genre ever!
Honestly, all you need to know is that this is a Sam Raimi/Bruce Campbell collaboration. If that doesn't do it, I can't help you. see more on Army of Darkness
What aging lady doesn't want to find a solution to growing old? Definitely the two leading ladies (Meryl Streep and Goldie Hawn) in this film. They seek out a woman with a solution to mortality so that they may be young and beautiful forever! Bruce Willis stars as the very homely, not-much-of-a-backbone-kind-of-guy stuck between them. see more on Death Becomes Her
Listen, I know this is technically sci-fi. But, based on everything else on the list, it just FEELS right. One of my favorite Tim Burton films. Jack Nicholson gets two roles (who doesn't need to see that?!) and at one point the aliens put Sarah Jessica Parker's head on a dog's body. More, please! see more on Mars Attacks!
