Ben Stiller will reprise his role as museum security guard Larry from the 2006 blockbuster "Night at the Museum."

Adams, best-known for her role in "Enchanted," would play an as-yet-undetermined historical figure and love interest for Larry, Variety.com reported.

Shawn Levy, who directed the first movie, will return to helm the second outing, which is set to hit U.S. theaters May 22, 2009.

The film is expected to start shooting in Vancouver in May.
