With over $1 billion already banked in just two movies, it was a foregone conclusion that Night at the Museum would return to wrap up the trilogy. And here, we have the first trailer for what is going to be the final installment in this insanelt successful Ben Stiller-led family series.

In Night at the Museum: Secret of the Tomb, Larry (Stiller) and the gang (Robin Williams, Owen Wilson, Steve Coogan, Ricky Gervais, and others) will head to London after Ben Kingsley warns them that their life-giving power source is running out. Across the pond, they’ll meet fellow security guard Rebel Wilson, Sir Lancelot (Dan Stevens), and undoubtedly get into many mishaps due to simple cultural misunderstandings.

The movie will be released on December 19 and will rake in a ton of money. Between now and then, prepare yourselves accordingly for an ungodly amount of advertising and promotions.
