I wrote one a long time ago called "Just One Star", and it was a slasher movie not that different from Scream, but I didn't rip anything off! Now, I'm working on one called "Ethereal", but I'm pretty sure everyone here would be bored stiff with that one!
But my husband, on the other hand, has about 20 screenplays which are all AMAZING, and I keep telling him to send them in, but I think he's scared they will steal them!
