 The night before filming began, Blitz took Thompson, Piazza and Yoo to dinner, insisting that they stay in character.Thompson, as Hal, was unable to tell the waitress what he wanted to order; Piazza, as Earl, obsessive-compulsively asked the waitress for a fresh straw each time she passed; and Yoo, as Heston, could not decide what to order and had the waitress explain the menu repeatedly.The purpose of the evening, according to Blitz, was for the actors to "be comfortable around each other inhabiting their roles without self-consciousness", as each of their roles required them to act in potentially embarrassing ways.
