Continuity mistake: After they get into the hotel and Waikiki is wheeling his brother in a chair, his hand is on the back and his thumb is sticking up in the air. The Nurse gives him a shot and it jump cuts to a close up, and suddenly his thumb is down. (00:09:30)
Continuity mistake: At the beginning of the movie Nya checks out of the leaking sink. The rag changes place after it cuts to her looking at the pipe, but she never moved it. (00:04:10)
Continuity mistake: When Rita is running toward the hanger in a scene that mirrors the first film, she is running on a long wood walkway. In the next shot however, she is on the dirt.
Continuity mistake: When Fish gets shot in the leg and runs out of ammo, we see him on the monitor still trying to shoot in vain. When it cuts to him, the slide is locked back and we see him release the slide and try to shoot. But in the next shot of him, the slide is once again locked back. Since we know he's out of ammo and he didn't reload or fire the gun, the only way for that to happen is if he manually pulled the slide back, which he didn't have an opportunity to do (not that it would even make sense to do).
