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.
I searched this morning, but I can't find any mention of this on the web. I was going to snap a picture of the notice to post on my blog, but my cell phone battery had died--and I probably would have been chased off by a security guard.
Blanking out chunks of audio seems a rather crude way of watermarking the film. Once again, it's the paying customers who suffer.
For reference, it was the Regal Cinema at Hacienda Crossing in Dublin, California. I was there to see Speed Racer in IMAX, so I didn't directly witness tampering with Indiana Jones.
