Forrest J Ackerman, the writer and creator of Famous Monsters Magazine has a lot of screen time with many interviews and footage of his ridiculously huge home collection of props and memorabilia from science fiction films throughout history. A large portion of the documentary revolves around Ackerman and just about everybody in the movie was influenced by Ackerman and his contribution to the genre fan-boys. However most of the film was about the great Ray Harryhausen and his special effects work. I almost felt that the whole movie could have just been about Harryhausen with the amount of discussion time they gave him. There are also a bunch of short films created by young Sci-Fi nerds in the 50's some of which are pretty interesting to look at. One of which involves greaser werewolves. The documentary comes to a end with c.g.i. which I find pretty consistent to what computers have done to these sort of movies in the first place.
Sci-Fi Boys wasn't a bad watch for what it is. Especially if you only pay two bucks for the dvd as I did. Check it out for a closer look at silly animatronics and stop animation.
