- Money, Dear Boy: Even more so than usual, the only reason the second movie got made, with Mario Bava in particular being involved only because he was contractually obligated to do so. He didn't even participate in the editing/dubbing process that assembled the English-language version of the film.
- Old Shame: Both Vincent Price and Fabian were totally frank as to how badly Girl Bombs turned out.
- Production Posse: Bikini Machine features a lot of people from American International's Beach Party movies, on both sides of the camera.
- Referenced by...: Rob Zombie's "Living Dead Girl":"Goldfoot's machine creates another fiend so beautiful it'll make you kill."
- Troubled Production: Price at least didn't much enjoy making Girl Bombs, due to the language barrier with the rest of the Italian production company. It was joked he even had trouble understanding Fabian, the one other guy who was theoretically speaking English. The film also underwent numerous script-rewrites attempting to satisfy its various international backers.
- What Could Have Been:
- The first film was originally envisioned as even more overtly campy, with musical numbers, but (to Price's reported disappointment) got rewritten as a (relatively) straight spy film.
- Frankie Avalon was going to reprise his role as government agent Craig Gamble in the second film, but bowed out due to his wife giving birth.
