Billy Crystal had written the part of Eddie for himself years ago, but director Joe Roth persuaded Crystal to take on the role of Lee the publicist, as he felt Crystal was too old to play the part by then.
This was Joe Roth's first picture as director in 11 years. Initially Billy Crystal was slated to direct the picture.
