I was thinking, to have a successful PRED.3, they would need a really good script writer. They would need a really great director, and a really believable cast of characters. Noone wants to see a PREDATOR 3 film with lousy direction, story, and acting (well, not me anyways).
This film would have to surpass the first film, and grab you by the balls. This film needs to have everything the first one had, and more. I think it would actually need to be set somewhere other than EARTH. Yeah, there would be alot of CG, but this is a new era of filming, and the times have changed. They could still have the "Man in suit" thing, but have it be on their planet, or on a colonized moon... something. I WANT DIFFERENT SETTINGS!!!
