Dignan introduces himself and Bob to Inez in the hotel room as Jerry and Cornelius. Jerry Cornelius is a character from Michael Moorcock's books such as "The Cure for Cancer" and "The Final Program".
According to the The Royal Tenenbaums DVD's director's commentary, Wes Anderson wanted the final scene to be set to Bob Dylan's "Billy (Main Title Theme)" from Dylan's score to Pat Garrett & Billy the Kid, but could not afford the rights to use it. (Anderson later used the song in The Royal Tenenbaums in the scene where Royal is kicked out of the house.)
Wes Anderson, Owen Wilson, and Luke Wilson made a 13 minute B/W short film called Bottle Rocket which was first shown at the USA Film Festival in Dallas. It met with a sufficiently enthusiastic response that they took it to Sundance where it came to the attention of screenwriter L.M. Kit Carson who directed it to towards Polly Platt and James L. Brooks. It was with their intervention that the team were able to get financial backing from Columbia to expand their short into a feature film.
Wes Anderson established such a good working rapport with cinematographer Robert D. Yeoman that he has been the director's cameraman on every one of his subsequent films.
James L. Brooks insisted that major work be done on the script so he had Wes Anderson and Owen Wilson flown to Los Angeles and set up in an office on $100 a day. Wilson tried to exchange his plane ticket for a bus ticket, hoping to pocket the cash instead.
