But for worst movie ever, I am going to go with worst memorable movie ever, which for me would be A Message from Space. This Japanese movie came out in the late 70s, and the plot was clearly a rip-off of Star Wars, which had only been released a year or so before. It was a big-budget movie, with some pretty decent special effects (such as huge sailboats that they used for spaceships), but it had some really odd twists on the Star Wars plot. The only explanation I could come up with was that the director thought Star Wars was lacking in some Japanese cultural values, and decided he could do better. For example, the bad guy Darth Vader counterpart wasn't really so bad himself; it was his mother who wanted to rule the universe, and he was just an obedient son carrying out her wishes. And the Death Star was actually a home planet to some of the good guys, but they gladly saw it destroyed to defeat the bad guy, and at the end they set out to find a new home.
