Answer:   All the President’s Men!
In this scene Washington Post newspaper reporter Carl Bernstein (Dustin Hoffman) is giving his notes from an interview to his partner Bob Woodward (Robert Redford), who is sitting at a typewriter. Many of Bernstein’s notes are written on napkins that he has stuffed in various pockets. As he pulls them out he says, “I’m a walking litter basket!” and an exasperated Woodward says line one. Bernstein replies with line two. He has just interviewed the bookkeeper (Jane Alexander) for Treasurer Maurice Stans of CREEP (the Committee to Reelect the President) and she was very reluctant to talk. Bernstein had jotted down notes as her sister got cup after cup of coffee. This movie tells the true story of the Watergate political scandal and the dogged investigative reporting of reporters Woodward and Bernstein that uncovered it (they are referred to together as a team as “Woodstein” by Washington Post editor Ben Bradlee, played by Jason Robards).
