Continuity mistake: When we first see Sherry's Mustang, it has a black convertible top, but later in the film when she and Big Momma ride into town the top is now white. (00:04:35 - 00:18:25)

Other mistake: When Big Momma is taking a shower, you can clearly see that the shower head is a mirror, with the water coming only out of the top, and when Big Momma bends over, you can also see her reflection in the shower head. (00:12:00)

Visible crew/equipment: When they are making the face of big momma we see the camera pass Malcom's back and then out again. When it reaches the other side you can a cameraman with a beard watching him in the mirror just before the other guy walks into the room. (00:17:00)

Continuity mistake: When Martin Lawrence tears the face mask and puts duct tape over it while cooking, it disappears when Mr. Roy comes for a visit just a few minutes later. (00:22:00 - 00:25:30)
Continuity mistake: Big Momma and the girl are in the kitchen and Big Momma tapes her face. In the next shot, no tape. (00:23:10)
Continuity mistake: When Big Momma's gentleman caller comes the door, Martin Lawrence takes out his gun and goes to answer the door. His gun is still in his hand up until the point when he answers the door. As soon as the door opens, the gun disappears. (00:25:20)
Continuity mistake: In the scene where Big Momma's gentleman caller comes to the door, Martin Lawrence runs over to the door and stands directly in front of it with both of his hands up gripping his gun. This can be seen in the shot when we see into the house through the window on the door. In the very next shot both of his hands are down. (00:25:25)
Factual error: In the movie, when the baby is born and Big Momma delivers it, the baby comes out without any blood and there's no umbilical cord. (00:34:20)
Continuity mistake: The sun was high in the sky at 5:45 a.m. I've lived in GA all my life and the sun has never been that bright at 5:45 a.m. (00:36:55)
Continuity mistake: When Big Momma wakes up to find that his face is peeling off and Shari knocks on the door, Big Momma goes out the window and his whole outfit comes off. He is completely dressed in a T shirt, sweats and tennis shoes. Why would he have clothes on under Big Momma's outfit, it would be too hot. (00:37:55)
Continuity mistake: When Martin rips the door bell off the door, throughout the scene it changes from wires hanging out with the door buzzer attached to just a bunch of wires. (00:38:55)
Continuity mistake: When Big Momma and Sherry park on the street in town the car they are in is a Mustang GT and when they get out and walk away the car is a Mustang LX. (00:42:10)
Continuity mistake: When Big Momma (Martin Lawrence) is in the place where Nolan supposedly teaches them to defend themselves. When Nolan is looking at Gertrude, you can clearly see a young face, with no wrinkles. Then when she is laying down on the floor, there is a very old face. They used a double for the scene in which she is hit. (00:43:20)
Revealing mistake: When the karate instructor throws the old lady, it’s a stunt double. This is evident because the face briefly changes, and the character’s wrinkles reappear after the fall. (00:43:30)
Continuity mistake: The sun was exactly as bright the evening they went fishing as it was at 5:45 a.m. (00:53:55)
Other mistake: When Nia Long and Martin Lawrence are sitting in the boat on the water, talking about Jascha Washington. You can see a fisherman in the background, but if you look close enough, you can see it's a fake person. (00:55:35)
Continuity mistake: Given that, the little boy chases fireflies (which don't light up until dusk). It was entirely too bright out for the fireflies to light up. (00:55:50)
Continuity mistake: Martin covers the girl with a blanket in the "evening" while the boy is chasing the fireflies. It is never cool enough in GA during the season of fireflies to warrant a blanket. Never. Unless there was some weird and unexplained weather phenomenon. (00:56:00)
Factual error: When Malcolm catches fireflies with Trent, they are glowing in broad daylight, which is not possible in reality. Firefly bioluminescence only occurs at night. (00:57:50)
Continuity mistake: When Malcolm finds the money he throw Sherri her necklace, but in the next shoot Malcolm is wearing the necklace. (01:17:10 - 01:20:15)






Answer: He tried opening the window, but it was stuck. He could also not have gotten through the window without making noise and being discovered. He just wanted to get out of the room without being seen.
