I had thought that Robert Rodriguez was directing the upcoming "Predator" sequel(are we calling it a sequel now?) but it turns out hes only producing it..in other words, putting his name on it!
According to the lads at Total Film, their sources are pointing to the Doomsday/Dog Soldiers man as all but signed to tackle the new pic.
Marshall is probably best known for "Doomsday" stateside, but by far his best movie is "The Descent". This guy can certainly bring the scary, but im not sure how he would handle the sci fi adventure elements. Time will tell, we await confirmation!
