1) The hazzan in the film is a good friend and former colleague of mine.
2) The Bar Mitzvah boy is a puppet. If I had to guess, I might suspect that he is even a distant cousin of one of my purim puppet play characters.
On a more serious note, I prefer the screen text to be more Hebrew for students to use, and less puppet-centered for adults, but it's still one of my new favorite teaching tools. Thanks Harold!
