Igby Goes Down (2002)

Revealing mistake: When Igby and his brother are removing the plastic bag from Mimi's head, her eyes blink.

Continuity mistake: When Igby's dad breaks the shower door, he breaks it with his right arm. The next shot has him cradling a badly cut and lacerated left arm.

Continuity mistake: When the spoon falls, 2 globs of the strawberry flavoured poison land on the carpet beside it. When the spoon is seen later, the poison is gone. (00:03:05 - 01:30:10)

D.H. Banes: Mimi. GET OFF THE maid.

Igby: Fuckwit.

Mimi: I take it you know that D.H. is your father?
Igby: No.
Mimi: Then I'm really glad I told you.
