I'm guessing it's just a mistake as the cover lists all 5 films and both versions of The Exorcist. So it must be 6 discs I presume. Looking forward to getting this, as I was always meaning to import 2 and 3 separately. After flogging my original copy of The Exorcist, it should work out about the same price as importing those 2 but with 2 extra films included. Yes, I actually like The Exorcist II
