For Richard LaGravanese, the Feb. 6 preem of Warner Bros.’ “Beautiful Creatures” at the Chinese underlined how much of an urbanite he is.

“I grew up in Brooklyn, and I live in Manhattan, so it was another world to be shooting in small towns in Louisiana last spring,” he said at the afterparty at the Roosevelt Hotel, replete with hanging moss and ghostly models. “I’m used to takeout, and you really couldn’t find food on Sundays.”

He credited Alcon toppers Andrew Kosove and Broderick Johnson with giving him ample time to script an adapation of the 600-plus pages of the novel by Kami Garcia and Margaret Stohl.

“I did ‘Behind the Candelabra’ in five weeks, but I need a year and half to figure out where the movie was in this very dense novel,” LaGravanese said.

Pic’s Alden Ehrenreich said growing up in Pacific Palisades was helpful in understanding the community dynamics of the film, set in South Carolina. “I know that Palisades is part of L.A. but it really does have a smalltown feel like in the film,” he added.
