You may never have heard of "Killing Gunther," but you certain know some of the actors in it -- Taran Killam (who also writes and directs it), Cobie Smulders, and Arnold Schwarzenegger to name but a few. It's something of a low-budget zany action-comedy about inept assassins trying to kill a good assassin. You might never suspect it at first blush, but it kind of works.
