After Dinner Speakers: Christopher Walken, Roger Sanchez, Andre Agassi

Walken had a small but juicy part as Diane Keaton's suicidal brother in Woody Allen's 1977 film Annie Hall. The next year he starred as Nick, the on-the-edge Russian roulette player in The Deer Hunter. The role won Walken an Oscar as best supporting actor and established him as a specialist in dangerous and unstable characters. By the 1990s Walken's creepy image had become a popular in-joke, with him being cast in films for laughs almost as often as for serious effect. His films include The Anderson Tapes (1972, with Sean Connery), At Close Range (1986, as Sean Penn's father), the James Bond movie A View To a Kill (1985, with Roger Moore) and Quentin Tarantino's Pulp Fiction (1994). After the 1990s Walken seemed to be everywhere. He was in the Fatboy Slim video for "Weapon of Choice," he was on Saturday NIght Live and he appeared in several films, including the horror series Prophecy (1995-2000), the animated feature Antz (1998), Tim Burton's Sleepy Hollow (1999, starring Johnny Depp) and Steven Spielberg's Catch Me If You Can (2001, starring Leonardo DiCaprio).
