In 1979, Mike Jittlov made a mark on Hollywood with the creation of the special effects short "The Wizard of Speed and Time" - and over the following decade, turned that ordeal into a movie! It has become somewhat of a cult classic, but emphasis on the cult (blog) because I'm sure most of you out there (blog post) haven't even heard about this one... which is a shame.
