Combined, the first two "Night at the Museum" movies earned just under $990 million in global grosses. With that in mind, here's the trailer for part three: "Night at the Museum: Secret of the Tomb." Ben Stiller returns to lead the fantasy adventure, with Robin Williams, Owen Wilson, Steve Coogan, Dan Stevens, Ricky Gervais and Rebel Wilson along for the ride as co-stars. Wilson and Coogan get peed on by a monkey at one point. Directed by Shawn Levy, this is expected to be the franchise's final installment. "Night at the Museum: Secret of the Tomb" is out on Dec. 19.
