Nudity in the trailer before this film

Was really surprised to see there were two seperate shots of bare breasts visible in the Return to the House on Haunted trailer on my dvd copy.
I was confused at first cause I didn't recall the film being R rated and checked the back. Usually don't let'em get away with stuff like that with films only rated PG-13.

Also was really surprised to see that film has a sort of interactive narrative, when the viewer decides which direction certain things are gonna take. Never heard of that being done before, or since. So I can't imagine it worked out too well for it...but hey, I'm mildly curious to seek that out and try it, if not just for the novelty of it.
