This box set is simply outstanding. If you have all the other William Castle movies out there this still has three that have been previously unavailable, including 13 Frightened Girls, The Old Dark House, and Zotz!. In addition, all the previous special features are included here from the rereleases of 13 Ghosts, Homicidal, Strait-Jacket, Mr Sardonicus, and The Tingler. And everything has been beautifully mastered. My advice is take those old discs and garage sale 'em and you'll already have paid for this box set. It would be wise however to remove the ghost viewer from your copy of 13 Ghosts since that item is inexplicably not included here. No commentaries which is ad but lots of other great special features including a feature length brand new documentary titled Spine Tingler! The William Castle Story.
