The name of the all-female rock band in the movie was "Diaper Rash" who were played by the real life rock group Vixen, who had a hit in the 1980's with "The Edge of a Broken Heart", and were, according to the film's production notes, touring the USA around the time that the movie was made and released.
The movie has its origins in an article published in the November 1983 edition of Penthouse Magazine written by the film's screenwriters Eric Alter and Steve Greene. It told of the true story of some "older rich dudes" who rented a summer beach house and enlisted a popular young surfer to help them meet girls.
The hardbody "most beautiful girl in the world" character's name is Suzie. When she exits the dressing room she returns Ashby's invitation with her name and number. Credits bill her as Jackie Easton, dressing room girl.
Screenwriter Eric Alter said of this film: "These guys are in their early 40s, successful and divorced. They spent their entire lives looking at these great girls and decided to finally do something about it. So they take all their money and invest it in a totally new lifestyle. They applied to dating the very same business tactics that helped them become financially successful. But there was still something missing and that's where Scotty comes in. He was like a magnet to girls. So they all made a little deal and, boom, they were in business!".
Writer-director Mark Griffiths was excited about the prospect of directing and co-writing his first comedy with Hardbodies (1984). Griffiths said: "I was chomping at the bit to do it. The whole scenario that Eric [Alter] and Steve [Greene] described in their Penthouse article holds tremendous potential for a hilarious teen sex-comedy, even though some more serious social undertones exist beneath the surface. There's always a certain chemistry in elements that don't necessarily mix, so when you combine these three otherwise harmless yet horny guys who are past their prime with scores of beautiful young girls and you use a suave young guy as the catalyst, the result is very, very funny".
What's Fall (Autumn) in the rest of the USA still looks like Summer in Southern California. So with beautiful warm weather for principal photography, and a "judicious use of extras and small resources", director Mark Griffiths was able to effectively re-create a typical summertime beach atmosphere. Even the one night they hoped for some rain for one particular scene, they got it. Griffiths said: "Luck was really with us throughout the shoot".
Director Mark Griffiths said of this movie's filming: "The first day of production we shot the title sequence, in which lots of gorgeous girls relax on the beach, listen to music, cover their bodies with tanning oil and generally hang out on the beach and in the water. When we moved locations, we piled five of the girls into a Mercedes 450SL and drove around with the top down. Well, we literally stopped traffic. People waited in intersections and cars made U-turns to get a better look at the girls. And when we had the film processed, even the guys at the lab said they could make a fortune selling tickets to our dailies!".
Many movie posters for the film feature the picture's "Hardbodies" title logo formed from squeezing a tube of white suntan cream onto the frontal suntanned hard body stomach of a female hotbody wearing a white bikini two-piece swimsuit with a bra top and panties bottom.
A lexical look into the world of hardbodies would reveal the movie featured its own unique jargon. This language included such terms as "Raamo" (= remodeling jobs - e.g. plastic surgery); "Tools" (= the elements of seduction e.g. a car, a jacuzzi); and "Dialoguing" (= thirty seconds of fast talk to get a phone number).
Self-proclaimed "experts on contemporary craziness", screenwriters Eric Alter and Steve Greene stumbled upon the idea for Hardbodies (1984) when they attended a beach party similar to that which the characters in the film throw. It included plenty of hard rock, hard liquor, and hard bodies.
