Thelma Schoonmaker and Martin Scorsese. Walter Murch and Francis Ford Coppola. Tim Squyres and Ang Lee. For many an editor, these longtime creative partnerships represent the most alluring and elusive of career ideals. For editor Andrew Weisblum, that ideal is well on the way to becoming a reality — twice over. Since 2007, Weisblum has cut all of both Wes Anderson’s and Darren Aronofsky’s feature films, ranging in style from the witty charm of Fantastic Mr. Fox to the demented psychodrama of Black Swan (for which Weisblum was Oscar nominated). Kicking off this year’s Manhattan Edit Workshop series “Inside the Cutting Room With Bobbie O’Steen” with an evening of clips and conversation last week, Weisblum reflected on his collaborations with these dramatically different directors. It was a study in opposites that proved again and again that it’s story, not style, that makes the editor.
