Revealing mistake: During the flashback scene where Max is describing the night of the kidnapping, the rainfall at the marina is obviously fake. The "rain" is being blown at an odd angle from an off-camera fan, and the surface of the water is practically still with no raindrops. (00:40:50)
Revealing mistake: When the Rangers arrive in the cave entrance of Maligore's temple (as Tommy cries "all right guys, this is it!") watch to the right of the screen, as Justin (the Blue Ranger) puts his arm against the stone cave wall and it wobbles, revealing it is a fake set wall. (01:11:40)
Revealing mistake: During his final speech Rudy projects a video of Donny Ray on a screen. When he rolls up the screen at the end, the projection of Donny Ray's face should still be visible on the wall behind. (01:57:45)
Revealing mistake: During the final battle in hell, when the army of Spawns rise up, there are some small errors to look for. First, during a few shots where the army is closer to camera, you can see the CGI army becoming "pixely." Also, you can see at least one of the Spawn floating in the air, not standing on the platform with the rest of him. Problems with the CGI rendering/animation.
Revealing mistake: In the scene, when the bug (actually another Kothoga monster) run out from the box that Margo has opened due to strange noises, there are visible wheels from the puppet of the bug. (00:48:40)
Revealing mistake: In the basement shootout, when a man is shot in the stomach, we see a close-up of his guts hanging out, and there's tape around it.
Revealing mistake: When Mr. Eddy is shot in the head and killed, there is an extremely quick shot that you can catch of what is a puppet's head exploding from the shot, before it cuts to Mr. Eddy falling back dead.
Revealing mistake: During the fighting scene outside the general store, Taggart hits one of the bad guys square on the nose two different times. After the second time, when the man is lying on the ground saying "Oh, my nose!", his hand's supposed to be holding his nose in pain but instead his hand is up around his forehead instead (his arm sort of blocks this but you can still see it).
Revealing mistake: When CHAM first go on stage, many of the extras in the crowd are drawn without much detail put into their faces. Also, despite them cheering and being extremely excited to see the trio perform, they are shown standing completely still and not moving whatsoever. (00:02:30)
Revealing mistake: At the end of the movie when Dusan sets the bomb for a time to blow up, he also sets his wristwatch, but if you look closely at the watch, he hasn't set it to a timer/stopwatch. (01:31:15)
Revealing mistake: In the locker of the Gentleman Caller there are multiple newspaper clippings. When Cross looks at the one talking about his niece, it just does not talk about his niece. The clipping is on camera long enough to be able to read without freeze frame, and it's talking about things like police brutality and apartheid (actual word used), entirely unrelated to the fake headline and picture caption.
