( CM ) - INDIANA JONES' SHIA LABOEUF was terrified of leaking details about the forthcoming blockbuster after director STEVEN SPIELBERG sued a big-mouthed extra.
LaBoeuf realised how serious Spielberg was about keeping production secrets, when he was first sent a script that was barcoded and watermarked to prevent duplication. He was also given a hotline number to call if he lost it.
The actor, who stars alongside Harrison Ford in Indiana Jones and the Kingdom of the Crystal Skull, also recalled the fate of 24-year-old Tyler Nelson, who was taken to court by Spielberg and his part reportedly cut from the film, after he leaked plot details in a newspaper interview.
LaBeouf says, "The joke I had was that Steven (Spielberg) had snipers following me. And if I ever slipped and gave up any tidbits, that was the end."
