Natalie Portman is attached as the lead in a new film version of “Wuthering Heights.”U.K. production company Ecosse Films, whose projects include “Mrs. Brown,” “Becoming Jane” and the upcoming “Brideshead Revisited,” is backing the pic. HanWay Films is handling worldwide sales. Olivia Hetreed (“Girl With a Pearl Earring”) wrote the script. Up next for Portman is a turn opposite Jake Gyllenhaal and Tobey Maguire in Jim Sheridan’s “Brothers.” The most recent bigscreen adaptation of Emily Bronte’s classic matched Ralph Fiennes with Juliette Binoche, but the Paramount release grossed just $624,643 in 1989. The definitive film take remains William Wyler’s 1939 version starring Laurence Olivier and Merle Oberon, which earned eight Oscar noms.
