Noah Bambauch's "Margot at the Wedding" was securely atop the iW BOT this weekend, according to final numbers posted this afternoon at indieWIRE.com. The Nicole Kidman-Jennifer Jason Leigh sister dramedy scored $81,035 from two locations in New York. Behind was the expansion of Joel and Ethan Coen's Oscar hopeful "No Country For Old Men" which took in a very impressive average of $20,782 on 148 screens, suggesting it may become one of the Coens' greatest box office successes. This week's indieWIRE box office article was posted yesterday. [Peter Knegt]
