Apocryphal maybe, but Olivier's apparent view on the general subject of acting vs the 'lived experience'
As legend has it, Olivier (a classically trained stage actor) and Hoffman had the following exchange during the shoot of Marathon Man.
“How did your week go, dear boy,” Olivier said.
Hoffman told him that he had filmed a scene in which his character was supposed to have been up for three days straight.
“So what did you do?” Olivier asked.
“Well, I stayed up for three days and three nights.”
Laurence Olivier then uttered this famous line, “Why don’t you just try acting?”
Did Hoffman reply by enquiring about acting and asking "Is it safe?"
