In the Rambo 4 (the search for matcho/homosexual ideology and cash) I have decided to see what films you can think of that are say The Hills Have Eyes versus Pee Wee Herman's summer camp holiday.
What you need is two film titles, a basic plot and a selling point. Nothing more. Maybe if we wrote all the crossover film ideas, maybe Holy-wood may stop producing them for fear of copyright infringement and copyright theft.
So who wants to be first?
