Because of their different acting styles and nationalities, some industry writers thought Connery and Hoffman might not work well together as close family members. "To the surprise of many," note Connery biographers Lee Pfeiffer and Lisa Philip, "the two superstars developed an immediate rapport and chemistry that translates onto the screen." And Lumet remembered: "Sean is extremely disciplined and Dustin is very improvisational, all over the place with his lines. I didn't know where it would end up, but Sean met Dustin improvisation for improvisation, and a great deal of richness and humor came out of it."
