Continuity: When Stanley is in jail, he put toilet papers on the toilet seat. But a few seconds later the toilet paper is not on the toilet.

Visible crew/equipment: Towards the end of the film you see the long haired baddie grab Milo by the hind legs (just before Milo puts the mask on). As Milo starts to change you can just about see the baddie who is holding his legs, except he is now a different person with brown curly hair, nobody who is seen prior or following this shot. Presumably he is the dog trainer.

Continuity: When Stanley Ipkiss first appears as the Mask, after having jumped through the end of hall apartment window with Mrs. Peenman shooting at him, he is approached by several thugs, one of which asks him the time. The thugs begin chasing him down the alley. The thug with the beard and baseball cap at the beginning of this chase is shirtless. Halfway through the chase he now has a flannel shirt on which is unbuttoned, (visible when he jumps over a barrel as it flies open). As he stops, now the flannel shirt is buttoned up to the very top button. The entire chase scene is 4-5 seconds long.

Continuity: When the Mask crashes Nico's party at the Coco Bongo, Nico shoots him. According to the sounds, the gun should have flashed 8 times but it only flashes 2 times.

Audio problem: In the scene where Milo jumps at the cell window to save Ipkiss, Stanley says "good boy," but his mouth doesn't move.

Continuity: When Tina kicks the mask out of Dorian's hand and Milo leaps through the air to catch it, he catches it with his mouth at the mask's chin, yet when he lands the mask has been turned round so the chin end is now facing the ground.

Continuity: When Dorian puts on the mask for the first time, right before all the smoke starts reducing, pay close attention to his goons. Some of them change position. (Clearly those were two takes pasted together, one with Dorian without the mask, and one with.)

Continuity: When The Mask first visits the Coco Bongo and dances wildly with Tina, they perform a series of impressive manouvers and The Mask then dips Tina and holds her in that position. At this moment, Tina is revealed to be a stunt double, not Cameron Diaz, just before the camera zooms into a close up of Jim Carrey.

Revealing: When Milo is trying to jump up to the jail cell, the brick wall is not brick but plastic as can be heard from his paws scratching on it.

Continuity: When Stanley is trying to get in the club, Dorian tells the bouncer to "lose him". The line is immediately repeated due to an editing screw up.

Continuity: When Dorian's boss shoots him in the stomach it switches from the boss to Dorian several times. Each time Dorian's buttons change colours from black buttons to white buttons to no buttons.

Continuity: When Ipkiss is in jail and he is summoning Milo, the dog jumps up through the bars. When Ipkiss pulls him through, one of the bars swings a little bit. It must not have been a very secure cell.

Continuity: When Dorian, as The Mask, breaks down the doors of the Coco Bongo, you see the door topple onto the doorman on the left. When the camera cuts back, he is on top of the door.

Continuity: In the very beginning, when the scuba diver is trying to open the chest and gets hit with the pipe, at first the pipe is held by a rope near the middle and when it's lowered into the water it is held by a chain at each end. After it hits the guy and is let go from the chains they are wrapped around three times.

Continuity: When Stanley is doing the Cuban dance watch his legs. Whenever the camera is behind him you can see him wearing black kneepads but when the camera is in front they aren't there.

Continuity: During the musical number "Cuban Pete", Jim Carrey's blue shirt is sometimes tucked in and sometimes is not.

Continuity: While in Mrs. Peenmans' hall, just before she shoots him, his hands switch places on the mallet. In the first shot, his left hand is on the bottom, right hand is on the top. In the other two shots, it is vice-versa.

Other: 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.

Continuity: When Stanley wakes up after his second night as the Mask, he is holding the mask. In the next shot, the mask has moved further up onto the pillow and Stanley isn't even touching it. Submitted by Brad

Continuity: In the club when Carrey is being shot by the goons when he's behind the counter, he jumps over the counter. Just before he jumps on the counter, you can see those were two separate takes. Pay close attention to the head on the left. Submitted by Dragon
