Plot hole: They seem to break a lot of rules in the main event between Mimi Lesseos and Jan Mackenzie's. They brawl outside the ring long enough to be counted out, choke outs on the ropes long enough to be disqualified are some examples.
Continuity mistake: Barbara Carrera's Priscilla has shoulder long hair most of the time yet at one point she's sporting a ponytail that reaches her waist.
Other mistake: In the opening credits of the movie, actress Luana Ravegnini's last name is misspelled as "Ravagnini" (00:01:20)
Continuity mistake: When Alex is speaking with Christopher in their dorm room she's wearing a pink top with the right shoulder down. Then it's pulled up in one shot before being back off the shoulder again.
Continuity mistake: When Fuller falls to his death, the mannequin used as his stand-in gets decapitated on its way down. It even makes a loud noise. When Fuller lands, however, his head is still on his shoulders.
Character mistake: Despite being blind, Erika Breen's able to locate light switches and door knobs throughout the movie without feeling for them like a blind person would do.
Revealing mistake: Obvious stuntman in a flame resistant suit when Eric's on fire.
Continuity mistake: Sammo Hung just left the bus to ride the bike with his cousin Jenny. They ride talking about Stallone and the USA, and the boxes of Nike shoes are tied to his bike differently when they arrive compared to when they started. (00:23:00)
Continuity mistake: The box of Marlboro cigarettes next to Buster's [Kiefer Sutherland] left hand did not have a lighter on top of it, but there was a lighter atop the pack after an angle shift. Buster was holding a newspaper with his left hand and had a cigarette in his right, so the lighter just suddenly appeared. Seconds later, the lighter was gone. (00:04:34 - 00:05:02)
Continuity mistake: John Ritter's beard goes from being real to fake throughout the movie.
Continuity mistake: Tanya O'Tabby's dress sleeves come and go when she's speaking to Sam Spayed (Garfield) for the last time. (00:25:00)
Other mistake: When the end credits start rolling, the note says the cast is listed in order of appearance. However, the cast is actually listed in a standard billing order based on importance to the story. For instance, Joan Severance is listed second despite not being introduced until more than 17 minutes into the movie, well after other characters who are also listed in the credits.
