There is a movie available on Netflix and on Amazon Prime called Capote (about Truman Capote), about 20 minutes in, he starts telling the story of his time in Italy with Humphrey Bogart and John Huston and it's joking and laughter, and then he says how he then got a call from his Stepfather telling him his mother's dead. His voice changes, his words become softer, like a well performed act, he explains his journey home, and the finding Joe there, who tells him to just, "Talk, talk, say anything so I don't break down." He uses this to get into the officer's head and so he'll let him into the case even more. It was brilliant Fractionation.
