Cruise, Aniston star in voting video

Tom Cruise and Jennifer Aniston have joined a host of stars in a video encouraging Americans to vote in the November 4 presidential election.

Justin Timberlake, Leonardo DiCaprio, Will Smith, Harrison Ford, Julia Roberts and Cameron Diaz also feature in the MySpace clip, in which they are instructed by filmmaker Steven Spielberg to sarcastically urge Americans not to use their vote.

Ford later dismisses Spielberg's direction, insisting that every vote counts.

"538 people determined the 2000 election," he said.

The celebrities each highlight their own reasons for voting and tell Americans to persuade five of their friends to go to the polls.
