What makes a movie a classic? (article link)

I liked reading this article from CNN Entertainment, an interview with Ben Mankiewicz from Turner Classic Movies; the question on the table is "What makes a movie a classic?". I agree with Ben for the most part, and I think a film has to have a bit of a shelf life to call it a classic. For example, I don't think anyone is considering Tarantino's new movie a classic, but in 25 or 30 years, it may be considered a classic. Look at the lasting impact of Pulp Fiction; it came out 25 years ago, and most people consider it a classic.
