Audio problem: [Blu-ray] When Mandy goes to wake up Red and Chloe, she says: "Hey! Hey, we need to get up, OK? Come on." The last two words were missed from the overdub, are not heard and are also missing from the subtitles. (01:08:15)
Audio problem: Guy flushes the toilet as he walks through the bathroom. The toilet is actually empty and the sound is an over-dub because there is no resistance on the handle when he pushes it down.
