Al Pacino has stated in interviews that he enjoyed working on this film, saying that Warren Beatty made ''a wonderful, artistic film, even though now it's like it doesn't even exist'', alluding to the notion that it is a movie that is barely talked about after all these years.
A 2-hour 15-minute version of the film exists, as confirmed by Warren Beatty in a 2002 interview. He said Jeffrey Katzenberg, then-chairman of Walt Disney Pictures, forced him to cut the film to 1 hour 45 minutes before release.
