Erika Christensen ("Swimfan," "Traffic"), Mike Vogel ("Texas Chainsaw Massacre"), Katherine Heigl ("Roswell") and Christopher Masterson ("Malcolm in the Middle") are now set to topline MTV's modernized "Wuthering Heights, CA" - which is slated for a May 6 start in Puerto Rico. The music TV network scored a hit, you'll recall, with Beyonce Knowles' "Carmen: A Hip-Hopera." Now they've moved the Emily Bronte tale to what's being described as "the tumultuous Mendocino coastline" for the story of a gal who falls for a poor musician but very unhappily weds the scion of a wealthy family instead.
