The Lord of the Rings/Star Wars crossover is a fairly established part of the LSW community. A crossover occurs when Gollum runs into clones, Qui-Gon Jinn battles Orcs, Mandos vs Orcs, or Obi-Wan Kenobi meets Frodo Baggins (and then faints.) It may exist as a stopmotion, short story, or simple comic.
