James L. Brooks' showbiz comedy I'll Do Anything is "The Musical That Almost Was" (after test screenings Brooks removed all the musical numbers in the film, turning the film into a songless romantic comedy). Matt Hobbs (Nick Nolte) is a hardly working actor who finds himself raising his 6-year-old daughter Jeannie (Whittni Wright) after her mother Beth (Tracey Ullman) is sent away to prison. Since Matt now has to support a daughter, he has to develop more regular work habits. As a result, he takes a job as a chauffeur for a William Castle-inspired schlockmeister named Burke Adler (Albert Brooks). As Adler develops a relationship with divorced test-marketing researcher Nan Mulhanney (Julie Kavner), Matt becomes romantically attached to beautiful development executive Cathy Breslow (Joely Richardson).
