According to an article at boingboing.com, Paramount is dropping the sound in the new Indiana Jones movie, in order to trace where pirate copies are coming from.
While at the cinema yesterday, I read a notice posted by the box office that Paramount has intentionally silenced bits of the soundtrack of _Indiana Jones and the Kingdom of the Crystal Skull_ in order to deter and track piracy. The notice acknowledged that the momentary silences were annoying but that it was out of their control. Basically it said, please don’t bug the manager if the sound drops out, unless it lasts more than a minute.
