Irony as They Are Cast: In the film, neither of the Aguilar brothers can speak any English. According to an interview in a Sports Illustrated "Where Are They Now" issue, Jaime Escobedo (Jose) and George Gonzales (Miguel) were in fact fluent in English and didn't know how to speak Spanish. They had to learn how to speak their entire dialogue strictly in Spanish before filming began.
Unintentional Period Piece: The film is so very mid-'70s, and a fine example of what a PG-rated film could get away with before the PG-13 rating came along. Just listen to 11-year-olds toss out four-letter words, racial epithets and ethnic slurs like there's no tomorrow and try to keep your head from exploding. Also watch as the kids douse each other in beer and see a then 14-year-old Jackie Earle Haley smoke like a chimney. In fact, some would argue that this movie would just barely avoid—or even get—an R rating if it was released today.
Kristy McNichol was offered the role of Amanda, and even successfully auditioned for the part. According to McNichol, the producers told her afterwards when they would begin filming and that she had to start preparing, but over one weekend they changed their minds, and she was disappointed to hear that they gave the role to Tatum O'Neal. She and O'Neal would co-star in the 1980 film Little Darlings.
