Have you ever seen a movie you completely forgot in a week — except for one moment in it, which stayed with you for years? When you think about it, a lot of movies are like that. Lisa and I recently took time out to recall a handful of the movie moments from this summer that we suspect will be sticking in our heads for a very long time. (You know, like that final machete thrust in The Expendables. Or Julia Roberts savoring the perfect plate of Roman pasta in Eat Pray Love.) Of course, some movies are better than others, but what makes a moment memorable has its own mysterious chemistry. Check out our video conversation after the jump, and then tell us about some of your favorite movie moments from this summer.
