Continuity mistake: In the bathroom after she feels sick, Jackie's wife is at the sink. After a brief conversation, another woman tells her she might be pregnant. She looks at the mirror with her mouth open as she thinks. It cuts to showing the mirror and her reflection shows her mouth closed.
Continuity mistake: When Lauda is going out from his pitstop he is blocked by Andretti's Lotus, but after the pitstop he overtakes Andretti on the track.
Continuity mistake: In the scene where Stallone gets hit by the UFC fighter, he doesn't see the hit coming because he gets hit from his right side. Later on, when driving his girlfriend home from the restaurant, he is still blind in his right eye and doesn't see the car coming from the right. However, during the Grudge Match, he is suddenly blind in his left eye.
Suggested correction: Clearly, he is blind in that eye. His trainer instructs him to stand to the left and keep Kid in his line of vision with his right eye.
