Ben Stiller reprises his role as Larry Daley, night guard of the Museum of Natural History, in the third and final instalment of the 'Night at the Museum' trilogy. As the magic of the Tablet of Ahkmenrah - the powers that bring the museum exhibits to life after sunset - begin to fade, Larry travels around the world in order to reunite members of his museum crew including Teddy Roosevelt (Robin Williams), Jedediah and Octavius (Owen Wilson and Steve Coogan) and, of course, Ahkmenrah (Rami Malek) to try to save the magic before it's too late.
