Special free episode! (Wait: All the episodes are free.) A mid-week show, though, with Tim and Will talking to Matt Singer, author of the terrific book "Opposable Thumbs: How Siskel & Ebert Changed Movies Forever." We discuss the show, film criticism, David Letterman and so much more. Enjoy!We hope you enjoy. Let us know what you think @griersonleitch on Twitter, or [email protected]. As always, give us a review on iTunes with the name of a movie you'd like us to review, and we'll discuss it on a later podcast.
