Leo Corrals Star Pals for Get-Out- the-Vote Video

Leonardo DiCaprio brings out the big guns for a get-out-the-vote video with an A-list cast including Tom Cruise, Julia Roberts, Harrison Ford, Will Smith, Steven Spielberg, and Justin Timberlake. Leo produces and appears in the spot, in which Spielberg directs the actors to use reverse psychology to get young people into voting booths by telling them not to vote.

Instructed by Spielberg to say, "Don't vote," Roberts says, "That doesn't make sense." Timberlake says, "I can do anything. I was in a boy band, OK?" Finally, Ford says, "You know what? I can't do it. It's not true, I don't believe it—537 people decided the 2000 election, and you want me to tell people that one vote doesn't count?" Notes Ryan Reynolds: "There are more Baldwin brothers than that." Also appearing: Cameron Diaz, Shia LaBeouf, Snoop Dogg, Neil Patrick Harris, Jason Segel, Zach Braff and Sacha Baron Cohen as Borat.
