Rival squads of sociopathic covert agents turn on each other with vicious glee when their underground facility is threatened with flaming death. The fun of Operation: Endgame lies in the cast: this is a pretty unlikely collection of assassins, played by the likes of Rob Corddry (Hot Tub Time Machine), Zach Galifianakis (The Hangover), and Emilie de Ravin (Lost), alongside more traditional Hollywood superspy types such as Maggie Q (Live Free or Die Hard), Ving Rhames (Dawn of the Dead), and Ellen Barkin (The Big Easy). Operation: Endgame also has fun with spook lingo (the agents are all named after tarot cards, ranging from the Devil to Temperance to the High Priestess) and extremely graphic violence (truly, at least half of the movie is watching the agents kill each other with improvised weapons, like paper shredders and golf putters). Corddry has the most fun with his part, giving the movie a jolt of energy whenever he appears, but the whole cast has their moment (though Rhames is wasted on a one-joke character). All in all, a bit flimsy, but Operation: Endgame knows that it’s trash and revels in it. A candidate for cult film status.
