Corrected entry: When Zack is about to watch 'Granny Panties' on his MacBook, the power in the house is shut off, which makes the MacBook shut off too. Since the MacBook is a laptop, in reality it would just switch to battery power instead of shutting off. (00:26:10)
Corrected entry: The camera used from the one-way-mirror in the coffee shop is never missed by the "I tell you!" boss, whereas Zack never replaces it and it is seen being carried into the shop every night by the 'white supremacist' camera man.
Correction: Since we don't ever see the boss after he's installed the camera, there's no way to know whether he's noticed the camera missing or not. He may have noticed it was missing and confronted Zack about it, who gave him an excuse. all off-camera.
Correction: Unless the battery was dead. This happened to me a few times when I had a laptop with a faulty battery that wouldn't hold a charge, forcing me to use the AC cord all the time.
