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: 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)
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.
