Hellraiser sounded like it would've been an amazing remake. It was supposed to be directed by Pascal Laugier, director of Martyrs, who I think would've done an amazing job, but negotiations fell through and now it doesn't look like it's gonna happen anytime soon.
I think it's pretty safe to say that Evil Dead will end up with an R18+. As far as violence goes they push some pretty heavy stuff into an MA15+ rating these days, but I think the tree rape scene alone will be enough to push it into 18+ territory, even if it isn't as graphic as the original. Sexualized violence, even if it's implied, tends to be a touchy subject.
