Ewan McGregor is headed for "The Island." The British star is in negotiations to topline the DreamWorks sci-fi film, which Michael Bay is set to direct. Originating as a spec script by Caspian Tredwell-Owen, "The Island" follows a "harvested being" who makes a bid to escape the utopian facility where he is being kept. Alex Kurtzman and Roberto Orci are on board as screenwriters. Walter Parkes, Laurie MacDonald and Ian Bryce are producing with Marc Haimes serving as the studio executive. DreamWorks is heading for a fall start. McGregor's credits include "Young Adam," "Big Fish" and "Down with Love." His upcoming releases include "Star Wars: Episode III -- Revenge of the Sith." Bay most recently directed "Bad Boys II." His other director credits include "Pearl Harbor, "Armageddon," "The Rock" and "Bad Boys." Bay is repped by WMA. McGregor is repped by CAA and Peters, Fraser & Dunlop in London. Kurtzman and Orci, who are also writing "Legend of Zorro" for Columbia, are repped by Broder Webb Chervin Silverman.
