Actor blows big chance with his giant mouth

Word is Steven Spielberg is threatening to cut scenes starring actor Tyler Nelson in the new Indiana Jones flick after he "leaked the plot line to an Oklahoma newspaper."

Apparently Nelson, 24, was so pumped about his role alongside Harrison Ford and Cate Blanchett in Indiana Jones And The Kingdom Of The Crystal Skull, he spilled the details and every major scene to his hometown paper, the Edmond Sun.

Possible SPOILER! Some of the things he said: Indiana Jones, played by Harrison Ford, and the Soviet army are in search of a skull made of crystal in the jungles of South America, the Russians take Jones hostage and blackmail him by threatening to kill his ex-girlfriend and Cate Blanchett plays an evil Russian who interrogates Jones.

Nelson said: "I saw Harrison Ford strapped to a chair and being interrogated." Nelson plays played a Russian soldier in the movie but you may not get to see him. He was allegedly fired by the producers for running his mouth. A rep for Spielberg says, "Who knows if he's ever going to work in this town again?" Ouch.
