In 1961, Landau and Unger turned to feature-film production, forming the Landau-Unger Company, which produced films such as "Long Day's Journey into Night" (1962) and "The Pawnbroker" (1964). The earlier film, a screen rendering of the play by Eugene O'Neill, was shown at the 1962 Cannes Film Festival, where its stars (Katharine Hepburn, Ralph Richardson, Jason Robards and Dean Stockwell) won the Best Actress and Actor awards collectively. The Landau-Unger Company also distributed "The Eleanor Roosevelt Story" (1965), which won the Academy Award for Best Documentary.
