Aha! Cheers
So the Bootleg edition is basically the director's cut. (As suggested in the title of the disc, I've just noticed)
Confused as to how they can have another disc simply titled "The Boomstick Edition", when "The Boomstick Edition" seems to be a 2-disc set that includes the director's cut
and theatrical cut. Sounds like the complete set will be both cuts of the film on DVD and Blu-Ray, and a final disc that includes either both, or one more of either the director's cut or theatrical.
Definitely proceeding with caution on this one, and will be prioritising the Necronomicon edition.
EDIT: Further investigation has revealed that it's actually the Television version that's the fifth disc in the set. Intriguing..
Found a video review from someone who's bought the box set and he's got the same blu-ray edition as me and he's said he'll be getting rid of that thanks to this.
