A great shot is the second scene in the bar where Jack is at the piano, finding some respite from his confusion. He finishes playing, but the camera stays where it is. The bar owner enters from the right, and we see only his back. He passes to the left of the screen, and says his lines. This scene is perfectly timed.
Life is Beautiful is an interesting movie.
It starts out, with it's quick cutting, close ups, and slapstick, looking like a Charlie Chaplin or Buster Keaton movie. It is light-hearted and thoroughly enjoyable. Like a minor annoyance in an otherwise idyllic life. The references increase in frequency, however, and the second half of the movie is set against the grim pallor of a concentration camp. The angst and horror of the camp is a grim counterpoint to the lightness of the first half of the movie.
