In principle, the Mockbuster is a bit like a movie with an Alternative Pornographic Name, but there's generally no nudity. It's not part of a pair of Battling Films, because it can't even afford the fare to get to the ring where the shows duke it out. A mockbuster is a movie that is suspiciously similar to another more popular, more well-known -- and, let's face it, more "real" -- movie, to the point of being the copy of an entire film. Why? Trying To Make Money Off A Popular Idea, of course. Has nothing to do with the Mythtesters or Phantomgetters.
