The first time brothers Jeff Bridges and Beau Bridges have acted in a film together. Some of the disagreements between the Baker Boys are based upon actual differences between the Bridges.
Michelle Pfeiffer hadn't sung in a year when she got the part of Susie Diamond. She had to practice for ten hours a day in the studio, and then took the tapes home with her to study them.
The iconic famous "Makin' Whoopee" scene on the piano was choreographed. It took six hours to shoot it. Michelle Pfeiffer only had one choreography lesson, and wore knee and elbow pads during rehearsals. The red velvet evening dress that Pfeiffer wears during the sequence was designed by the film's costume designer, Lisa Jensen.
Beau Bridges was not balding, but the script called for him to have a bald spot as Frank. In a 2014 interview, it was revealed that Jeff Bridges cut the bald spot into Beau's hair. Jeff explained, "So he let me - we had a couple of glasses of wine - and he allowed me to cut the bald patch on the back of his head." "Stupid move," Beau shot back.
