Eva Longoria and Michael Douglas' Basketball Battle  6/26/05

Actress Eva Longoria and Michael Douglas played practical jokes on each other throughout the filming of new thriller The Sentinel after discovering they're huge fans of opposing basketball teams.

The Desperate Housewives star is a fervent fan of the new National Basketball Association champions San Antonio Spurs, while Douglas supports the Miami Heat, and the two waged war with each other on the set of the movie in Canada.

Longoria says, "I decorated his trailer with Spurs everything and then I run around the corner and I'm about to shoot the gun (in a scene) and the whole crew has Miami hats on."

Douglas, who both produces and stars in the movie, ordered the hats directly from Miami Heat officials to get his own back on his cheeky co-star.
