While we were looking for directors on Manchurian Candidate, producer Scott Rudin asked if I could help find a new ending for Changing Lanes.  They’d tried several none had worked.  It was classic Greek tragedy, escalating revenge, but the bitter, bleak endings simply did not hold in a modern story.  It asked for some resolution, some catharsis and escape from the spiraling conflict.  I spent a week in a tiny dark room at the W Hotel in New York, wrote a series of linking scenes, met Jonathan Demme (and he agreed to do Manchurian).  By the time I returned to the West Coast they were shooting the new material for Changing Lanes, and the movie was released less than a month later.
