Corrected entry: When Tina goes to the police station to see Stanley to tell him about what is going to happen that night, Stanley tells her to leave town so that she will be safe. A few minutes later, when Dorian and his men have Tina cornered in an alleyway, one of them turns up holding a suitcase and says, "Look what I found in her car." But there was no time between Tina leaving the police station and her being cornered in the alleyway for her to have been able to go home and pack clothes.
Corrected entry: After Dorian absorbs the bullets that Nico shot at him, he opens his mouth and we can see that the bullets have their shells again instead of just the projectiles.
Corrected entry: When Tina Carlyle performs at the Coco Bongo she is first shown behind some branches on a podium, then she is seen walking down steps to the stage. But there were no steps on the podium for her to walk on.
Corrected entry: In the beginning of the film when Tina walks into the bank, Charlie tells Stanley to look at 3 o'clock, which is their right. But the two stare straight ahead, which would be their 12 o'clock.
Corrected entry: Before Carey puts on the mask for the second time, he looks at a picture of Tina, then crumples it up. Then, after he has the mask on, he picks up the picture. But there are now no wrinkle marks in it.
Corrected entry: The first time Jim Carrey becomes the Mask, he approaches some thugs. Ipkiss then honks a guy's nose and pulls his underwear over his head. Then the Mask runs away and the thugs follow him. As they reach Ipkiss, the man no longer has the underwear over his head - I doubt he could put it back in 2-3 seconds.
Corrected entry: When Dorian is playing golf in a golfsimulator, he hits a ball from a tee placed in an other mans mouth. He uses either a 5 or a 4 iron, and he doesn't have a full swing at all, but anyway the golfsimulator says that he hit 205 meters, which is impossible with a 5 or 4 iron and not a full swing.
Corrected entry: When Dorian first gets the Mask from Stanley, he asks how it works. Stanley says to just put it on. Yet later in the film Dorian says "The sun's going down. Time to get changed for the party." He is never told that the Mask only works at night, yet he waits until nightfall to put it on.
Corrected entry: Stanley is told by an expert that the Norse god Loki caused so much mischief that Odin banished him from Valhalla, implying that Loki ended up in the mask. According to Norse mythology Loki got on Odin's bad side because he helped kill Balder, Odin's favorite son. He was then tied to the mountain with acid dripping down on his head. His wife stood with a bowl above his head and gathered the acid, but whenever it was full and she had to empty it acid fell on Loki who struggled, which is how Norse mythology explained earthquakes. There are no other "versions" to explain why Loki left Valhalla and what happened to him.
Corrected entry: In the same scene, one of Dorian's goons gets bitten in the butt by masked Milo and his pants rip. But later on his pants are OK.
