Continuity mistake: When Miss Trunchbull is talking to Amanda Thripp in the school yard, watch Amanda's left pigtail. When she says, "You mean my pigtails?"

Continuity mistake: At the end when Trunchbull throws the boy out of the window, we see when he is flying back in that the brown car is parked about 6-8 feet away from the building and bushes. When Trunchbull runs out of the building to the car after having food thrown at her, the car grill is now almost touching the bushes and the car is further from the stairs. (01:26:00 - 01:28:00)
Continuity mistake: At the scene where Ms. Trunchbull is under attack by the children in Matilda's class, she tries to catch Lavender, a brown girl in purple dungarees. At the time Ms. Trunchbull runs into Lavender, both sides of her dungarees are buttoned. Then Lavender is lifted by Mathilda to hold on to a pipe at the ceiling. At the very single shot where she is holding onto that pipe you can see all side buttons of her dungarees are loose. (01:26:50)
