“Zero Dark Thirty” Oscar nominee Jessica Chastain got a visit from Oscar-winner Liza Minnelli at her Broadway show, “The Heiress.” Spies saw Minnelli and her pal Sam Harris at the play last week before they slipped backstage to visit Chastain and the cast. Minnelli won an Oscar for Bob Fosse’s 1972 film “Cabaret,” which is getting a 40th anniversary screening Thursday at the Ziegfeld Theatre, where it originally premiered. Minnelli and Harris were also earlier seen having dinner at Sardi’s.
