Indiana Jones' Shia LaBeouf was terrified of leaking details about the forthcoming blockbuster after director Steven Spielberg sued a big-mouthed extra.

LaBeouf 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.
