In honor of Michel Gondry's new flick, Be Kind, Rewind, Filmmaking Frenzy held a contest for parody/remakes. The best one so far is The Thing by Team Syracused. They've got flames going, fake blood, even a severed head prop!
Beware though, it's very hit or miss, especially the ones starring people in their mid forties. For example, this Lebowski one is okay, but another one I saw was just crap made by some nerds.
And if you have a place in your heart for David Bowie, you owe it to yourself to watch the Labyrinth parody.
