John Leguizamo was originally set to direct the film, but after being cast as Jorge as well, as serving as executive producer, Frank Whaley stepped in as director as well as staying on as a producer.
Toward the end of the movie when Joe's father is driving to pick him up, he passes a driveway with a Jeep Wrangler parked in it. If it were the 1970s, it would have been a Jeep CJ-5 or CJ-7.
Although the film is supposed to take place during the 1970s, Joe is seen wearing a name brand underwear with the company logo on the waistband. This particular brand didn't produce that style until the late 1990s.
