Were the Film Collection simply the movies themselves, it would be a solid addition to any cult collector's treasure vault, but what makes the set truly special is the wealth of extras that accompany the features. Brand-new making-of documentaries are offered for each of the films save Zotz, 13 Frightened Girls, and The Old Dark House; each discusses Castle's elaborate promotional gimmicks in detail, from The Tingler's ""Percepto"" (electrically wired seats) to Sardonicus's ""Punishment Poll"" (cards given to audience members to decide the fate of the title villain). Extensive news clips, photographs, and comments from a host of fans and critics, including David Del Valle, David Skal, Bob Burns, Castle's daughter Terry, Strait-Jacket star Diane Baker, and The Tingler's Darryl Hickman (who seems bemused by the film's favored status), make these featurettes invaluable to Castle completists. The gimmick in 13 Frightened Girls is given plenty of coverage in its extras--its cast of schoolgirls was culled from an international contest, and each was featured in a special intro shot for their respective country--while Strait-Jacket offers Crawford's costume screen test as well as a trial run at lopping off costar George Kennedy's head (!), plus an amusing promo clip in which Castle, Bloch, and their star plot out the perfect murder. There are also two episodes from the Castle-produced supernatural TV anthology Ghost Story (one under its retitle, Circle of Fear), both of which feature the man himself in typically grandiose cameos, as well as original U.S. and some international trailers for each title. And if that's not enough, there's also a fifth disc devoted entirely to the 2007 documentary Spine Tingler! The William Castle Story, which details his life and career of making people scream, via archival footage and a who's who of horror and science fiction, including Joe Dante, John Landis, Roger Corman, Fred Olen Ray, the late Forrest J. Ackerman, and countless others, each weighing in on the joys and thrills of William Castle's feature films. --Paul Gaita"
