The script was written back in 1993. The writers brought it to the attention of Steven Soderbergh who then took it to the then president of production at Universal Pictures, Casey Silver.

Star-director George Clooney and his co-star Renée Zellweger premiered this film in Clooney's hometown of Maysville, KY on March 24th, 2008. In 1953, his aunt Rosemary Clooney had premiered a film of her own, The Stars Are Singing (1953), in the same town, though not at the same theatre. Roughly 3,000 fans attended the red carpet event while 200 VIPs were hand-selected to watch the film. An additional screening was held afterward with 100 lucky winners winning 2 tickets apiece from a raffle drawing.

Governor of Kentucky Steve Henry and his wife, Miss America 2000, Heather French Henry.
