PLOT: A motley crew of assassins team-up to take down the world’s greatest hit-man, Gunther (Arnold Schwarzenegger). REVIEW: Writer-director-star Taran Killam has his heart in the right place. An avowed action fanboy with a love of James Bond and the action Gods of the eighties, KILLING GUNTHER is his attempt at a globe-trotting action romp, with himself as the star.
