LOS ANGELES--(BUSINESS WIRE)--The greatest figures in world history, as well as nature’s most impressive creatures, will come to life for an entire night for pajama-clad family “explorers,” as part of special promotional events for the action-adventure-comedy NIGHT AT THE MUSEUM.

Sleepover events are scheduled in New York (Museum of Natural History), Los Angeles (Museum of Natural History), Chicago (Field Museum), Oklahoma City (Omniplex Museum), Salt Lake City (Salt Lake City Natural History Museum), Vancouver (Vancouver Museum), Calgary (Royal Tyrrell Museum of Paleontology) and Toronto (Royal Ontario Museum). NIGHT AT THE MUSEUM star Ben Stiller will appear at the New York event, leading over 300 guests through a special “Flashlight Tour.”

Activities will be tailored to each location, including Flashlight Tours and other interactive activities, plus screenings of the film and a special museum breakfast. Each sleepover participant will receive a NIGHT AT THE MUSEUM flashlight and blanket.

In NIGHT AT THE MUSEUM, Ben Stiller portrays a graveyard-shift security guard at a museum of natural history, where the exhibits come to life at night…literally. Mayans, Roman Gladiators, and cowboys emerge from their dioramas to wage epic battles; a Neanderthal burns down his own display in his quest for fire; Attila the Hun pillages his neighboring exhibits, and a T-Rex reminds everyone why he’s history’s fiercest predator. Amidst the chaos, the only person the guard can turn to for advice is a wax figure of President Teddy Roosevelt (Robin Williams), who helps our hero harness the bedlam, stop a nefarious plot, and save the museum.

The film opens everywhere December 22.
