The film's real-life character, Ronnie Shedio, served as a personal assistant to Errol Flynn and also as a consultant to the movie's directors before his death in 2007.
Beverly Aadland's third husband, Ron Fisher; his daughter, Aadlanda; and her daughter, Navaeh, visited the set in Atlanta and played extras in an airport scene.
It took Glatzer and partner Wash Westmoreland 10 years to track down the interview tapes Florence Aadland had made for her book 'The Big Love'.
Errol Flynn died at 50. Since the time line depicted here is most certainly 1957, when he was 49, Kevin Kline is 18 years older (or more) than Flynn would have been during the events depicted.
