Killing Gunther trailer features Arnold Schwarzenegger as an assassin

Arnold Schwarzenegger is going back to being funny on purpose. 

He stars in Killing Gunther, the upcoming comedy written and directed by SNL alumni Taran Killam. Set in the world of contract killers, the movie follows a group of young, undisciplined assassins who hire a documentary crew at gunpoint to have proof that they're responsible for finally killing Gunther (Schwarzenegger), the most notorious hitman of all time. However, Gunther is the best for a reason, and he quickly learns about their plan.

The movie co-stars Bobby Moynihan, Cobi Smulders, Hannah Simone, and Allison Tolman, and will be available to watch on Ultra VOD beginning Sept. 22. It will hit select theaters and On Demand on Oct. 20.
