When Paul Giamatti made "Sideways" with Alexander Payne, he stayed in a little house in the middle of a large vineyard. At the end of a day of shooting, he would drive home in darkness, with the hills of Napa Valley around him. Giamatti was then a respected character actor, but this was one of his first times as the lead. And he couldn't believe it. "I remember Alexander saying, ‘You two guys are going to do it,’" recalls Giamatti of himself and Thomas Hayden Church. "And we were like, ‘Seriously?’"
