• Cowboy Bebop at His Computer: The game's manual claims that Castle Wolfenstein was released for the Apple II in 1983 and was about infiltrating a Nazi headquarters to assassinate Adolf Hitler with a bomb. Castle Wolfenstein was released for that system in 1981, and the plot described was actually that of Beyond Castle Wolfenstein from 1984.
  • Development Hell: The film adaptation. Cult director Roger Avary was tapped to write and direct, then was sent to jail for vehicular manslaughter. When he got out, the funding had dried up. Supposedly he's still attached, but few people really want to fund a video game movie in the age of comic book movies.
  • Milestone Celebration: Return to Castle Wolfenstein was released roughly twenty years after Castle Wolfenstein, the first game in the Wolfenstein series.
