Michael Fassbender was a guest on the Late Show with David Letterman yesterday. The star of Shame opened up to David about a variety of topics, including the amount of time he spent nude on the set of the Steve McQueen-directed drama. Michael Fassbender's full-frontal nudity is a topic David wanted to dwell on for a moment, but the actor was in a mood to joke. Of the NC-17 film, Michael teased, "I thought there would be a three part franchise in it, at least!" Michael also touched on his upbringing from his birth in Heidelberg, Germany, to childhood in Ireland, and life as an adult in London.
