Judging from Martha Marcy May Marlene, one of the most talked-about feature films currently showing at the New York Film festival, relative newcomers writer/director Sean Durkin and actress Elizabeth Olsen (younger sister of Mary-Kate and Ashley) were born with the right gene. This new thriller is so tight and poised that it appears to be the work of long-collaborating veterans (it may prove difficult for them to live up to this standard through the rest of their careers but that's a good problem for them--and us--to have to face).
