Mila Kunis and Kate McKinnon are the onscreen BFFs you never knew you needed. The pair star in the upcoming action film The Spy Who Dumped Me, which sees Kunis going on the run in Europe after her ex-boyfriend (Justin Theroux) turns out to be a spy (yes, we're getting Knight and Day vibes, too) (You've never seen Knight and Day?!) (Shame on you, honestly). Fortunately she has McKinnon to help her with everything from swallowing flash drives to stealing cars. Watch the hilarious trailer before it hits cinemas on July 6.
