Peter Debruge Chief Film Critic Shia LaBeouf doesn’t appear until more than 20 minutes into “Henry Johnson,” a new David Mamet play making its world premiere at the Electric Lodge in Venice, Calif. The play amounts to just four scenes, barely more than an hour in all (plus an unnecessary 15-minute intermission). LaBeouf is on stage for just two of them, but the instant the film star materializes, something electric happens.
