In the scene where Benjamin is talking to his grandfather while fishing on the pier; at one point the background behind Ben is filled with sailboats while the camera is on him. The shot switches to his grandfather for a few lines and when it switches back to Ben, just a few seconds later, the sailboats are all gone. There was not enough time for the boats to have sailed out of the scene.
In the scene after Benjamin jumps into the pool at his party, he has changed his into dry clothes. He changes into a green polo shirt. When he walks outside, after changing, he is now wearing a striped blue shirt and Zachary is wearing the same green shirt that Benjamin was wearing just a few minutes ago.

In the scene where Zachary is talking to Benjamin at Hebrew school about his fear of reading the Haftorah in front of a crowd, Zachary can be seen mouthing the words Benjamin is saying, "...cool up there at your Bar Mitzvah".
When Benjamin is reading his Haftorah at his Bar Mitzvah, he fails to say the required prayer that precedes it. Instead, he goes right into the Haftorah portion itself.
