According to The Hollywood Reporter, Stephen Sommers has signed on to direct Night at the Museum for 20th Century Fox. While taking on the Fox film, he is stepping aside from writing/directing/producing chores on Paramount Pictures' When Worlds Collide. Steven Spielberg, who directed Paramount/DreamWorks' summer sci-fi hit War of the Worlds, is boarding When Worlds Collide as a producer and will develop the film for Paramount.

Museum, which is loosely based on Milan Trenc's children's book "The Night at the Museum," will be produced by Chris Columbus and Michael Barnathan through their 1492 Pictures. Sommers and partner Bob Ducsay also are producing through their Sommers Co.

The script was penned by Thomas Lennon and Robert Ben Garant, with revisions by Scott Frank.
