Especially if, like me, you're a William Castle fan. Perhaps that's why this movie is rarely shown. The script here is rather convoluted as the story is basically a sci-fi mystery that slowly gets revealed.
Not much that happens makes sense. For instance, why is it necessary to convince the subject he's in the 1960s? While an unconvincing explanation is made, we all know it's to save money on sets. Also what purpose does Greta Baldwin serve? Besides an interlude of eye candy her character doesn't make much sense in the context of the movie.
The actors are mostly familiar faces, likely wondering how they got talked into this. While Chris George gets top billing he really doesn't have much to do except act disoriented and annoyed.
The FX are pretty standard for a 60s sci-fi B movie or TV. More or less on the level of the original Star Trek series of the same period.
While I haven't seen all of Castle's films, I'd have to place this one at the bottom of the one's I've seen. Overall I'd say skip this one and rewatch any other film from his "gimmick" period. They're all way more fun than this mess.
