Next for "Scary Movie" scribes the Wayans Brothers is a spoof of science fiction films – a’la "Signs" and "Independence Day". Keenen Ivory and actors Marlon and Shawn Wayans have pitched a pair of comedy propositions which DreamWorks, Fox, Universal and Revolution all are bidding on. The asking price was $4 million against $15 million for the two movies, which would be set against a gross of around 15%. The deal also calls for Marlon and Shawn to topline a comedy in which they would tart up in drag. Keenen will direct both new films in the deal. But next…"Scary Movie 3".
