George Lucas and Lucasfilm
One of George Lucas' early short films was Electronic Labyrinth: THX 1138 4EB, later remade into the 1971 feature film THX 1138. After the film, references to 1138 (and sometimes to THX) are scattered throughout Lucas' films, Lucasfilm productions and LucasArts computer games.
