Robert Downey Jr. has said of this film at the Robert Downey, Jr. Film Guide website: "At the time, I was working at a restaurant called Central Falls as a busboy, a lot of friends of mine were all auditioning for this. I had four weeks work in 'Baby It's You', and I told all my friends I was now, officially, a major talent and film star, and then they cut my scenes out. You don't even see me except in one scene, you see me in the background, until this self-indulgent actress leans forward to try and get more camera time. My friends called it 'Maybe It's You'."
John Sayles has said of this film: "'Baby, It's You' is about rock 'n' roll. It's about firsts: first sex, first love, first drugs, first loss".
When Paramount threatened to re-cut the film after poor test screenings, John Sayles threatened to take his name off the film. Paramount relented, and released the Director's Cut.
Some critics disliked the use of Bruce Springsteen on the soundtrack, feeling that it sounded too contemporary for a film set in the 1960s. John Sayles felt that the songs reflected the spirit of the film itself.
