Kate Winslet (pictured), Tony Kushner, James Ivory and Jeff Rosen hosted a screening and reception the other night at the Tribeca Grand Hotel for “Crazy Heart” stars Jeff Bridges and Maggie Gyllenhaal. Winslet gave an emotional speech, saying the film — starring Bridges as a country singer trying to get off the booze and into the arms of a good woman — “made me come undone.” Other guests included Billy Crudup, writer/director Scott Cooper and producer Judy Cairo.
