I saw an advert for that love story film which is the same as scary movie but about romantic comedies instead, on the advert it very specifically said it was written by "TWO OF THE SCARY MOVIE WRITERS"
Although if all 6 (or whatever) of them could not write their way out of a paper bag, the chances of only two of them writing a good script are about as good as my dead grandmother writing a good script, and she's dead!
