Other mistake: When Tommy's lying on the mat unconscious, her arms are at her sides. When she's shown from Rosa's vantage point, they're spread out.
Other mistake: If Terrible Tommy's the world champion then where's the title belt she should be wearing?
Other mistake: It makes no sense for Hilda to be on the ring apron during Rosa's match with Terrible Tommy much less be in her ring gear when she didn't wrestle on that card.
Other mistake: When Tommy tries splashing Rosa during their match she hits the ring mat with her chest and stomach yet seconds later she's somehow knocked out. I never saw her head hit after multiple viewings of that scene.
Other mistake: Rosa and her co-worker couldn't possibly be watching Terrible Tommy as she and Princess War Star enter the arena as the movie starts. Because later on they're shown wrestling in that same arena wearing those same outfits wrestling, a sign that scene was shot at a different time or a part of the wrestling scene where Rosa and another wrestler are watching Tommy.
Other mistake: Tommy's got blood coming from her left nostril even though Rosa only twisted it, she didn't do anything hard enough to cause a nosebleed.
