Rushmore (1998)

Continuity mistake: When Max goes to talk to Miss Cross after the initial opening of the Aquarium, she is sitting in a playhouse with several little kids around her. Max approaches and ducks under the low roof so he could sit down and talk, but somehow all the kids around Miss Cross have disappeared.

Backgammon Player: Did you hear they're teaching Japanese next year?
Max Fischer: That's the rumor.
Backgammon Player: And they're canceling Latin.
Max Fischer: What? I tried to get Latin canceled for five years! It's a dead language, I always say.
Backgammon Player: Well, I guess they finally heard you.
