The short two hour look at a couple of Scifi subjects via film clips (from trailers) is a companion piece to the similar One Hundred Years of Horror. This is a history of science fiction told through a few interviews as well as with clips from various movies culled from movie trailers which are in the public domain. Like the horror film this film also has a longer 26 part version. However where the short Horror film made you want to see the longer version (which is a masterpiece of Horror history when viewed in its entirety), this makes you want to move on to the next thing. Its a shame since the longer 26 part version of this film is actually pretty good. Its not the horror series but its still fun to watch thanks to all of the clips that it contains. The short version is narrated by Christopher Lee who simply links some of the segments with some oblique references.(Lee is not in the long version). Given the choice I'd opt for the longer version and skip this short one.
