GL could prolly care less wat people do with his movies. he said that he made the movies to inspire young filmmakers. so i doubt he'll sue and i think he'll really look hard into wat ady's doing and i imagine he's very impressed.
just think, the SSE by GL. his enhanced version along including adywan's classic vision of wat star wars should be. now if FOX got wind of this, they might sue, so that's wat i'd worry about. however since lucas owns the rights i think adywan will be fine.
btw. HAPPY BDAY ADYWAN!!! :D
