The question “Who has the right to play God?” is at the center of this comedic tale of a group of friends at a Jerusalem retirement home who construct a machine for self-euthanasia in order to help a terminally ill pal. With a dream cast of septuagenarian talent, a finely honed visual sense, and superbly ironic comic timing and dialogue, this compassionate film doesn’t belabor the ethics of assisted suicide but instead treats this tricky topic with rare sensitivity.
