I've seen plenty of productions of "Long Day's Journey into Night," but I just watched Sidney Lumet's 1962 film. If it wasn't shot at the Monte Cristo cottage in Waterford, Connecticut, it certainly looks like it was. The stage version starred Frederic March and Florence Eldridge; the only carry-over from Broadway is Jason Robards (still Jason Robards, Jr., at that point). Katharine Hepburn and Ralph Richardson play the parents, Dean Stockwell (who knew he could really act?) plays the tubercular brother. Andre Previn did the score. It's fantastic.
