Director Terence Davies and actress Rachel Weisz discuss their new movie, “The Deep Blue Sea.” Rachel Weisz plays the wife of a high-WASP judge, a free spirit trapped in a passionless marriage. The film is an adaptation of British playwright Terence Rattigan's 1952 play, and it opens March 23 at the Paris Theatre and the Angelika Film Center. Terence Davies’ films are also being presented in a retrospective at BAMcinematek through March 27.
