Audio problem: When the Geckos shoot Chet Pussy, the sounds of gunfire don't match the visible gunshots. (01:00:25)
Audio problem: When Andy says to Debbie "How do we do it in a hammock?" his mouth doesn't move to the word 'hammock.' (00:46:05)
Audio problem: When Emily picks up the tooth from the box, she says "ew" but if you look in the mirror her lips don't move.
Audio problem: In the scene after Norman goes for a late-night swim, when he's telling Maureen that he slipped in the mud, you can see that his mouth never moves, yet he speaks the words "I slipped in the mud."
Audio problem: Right before Charley gets thrown into the closet doors, Jerry has him by the throat threatening to kill his mother if she wakes up. In the shots of Charley trying to free himself of the grip, Jerry's lips are moving but no sound can be heard. (00:28:15)
Audio problem: Nancy shouts, "Yay Chris! Go long! Go for the pass, baby!" at football practice, and her voice is so distorted that the viewer can easily tell the line was added post-production (with too much gain).
Audio problem: In the scene where Rose is talking to the demonic form of Alessa, watch her mouth as she says "Christabella will find Sharon." Alessa's mouth doesn't match every word she says.
Audio problem: When Steve says "What?" to Kirsty at the pet-store, it's pretty painfully obvious that the line was dubbed in during post. The audio is much more loudly spoken than he appears to be speaking. (Several characters were redubbed with American accents in post. Presumably this is the reason for the inconsistency). (00:45:33)
Audio problem: Throughout the entire film, much of the audio is inaudible, and in several key scenes (including most scenes set in cars), you can hear a loud sort-of "crunchy" and windy sound from the microphone.
Audio problem: At the beginning of the movie, a local errand guy delivers a box to Poirot from a gondola. The actor is supposed to be speaking Italian in his first phrase, but he says "Segnor Poirot, lo pesce!" (Mr. Poirot, your fish!), totally off in accent and grammar, obviously from an English-speaking actor poorly faking an Italian accent. Moreover, the box does not contain fish, but turns out a few minutes later to be a box of chocolates. In fact, the Italian version redubs this line entirely and the guy says the equivalent of "Mr. Poirot, your sweets" in a Venetian accent ("Sior Poirot, I suoi dolcetti!").
Audio problem: When Trevor is explaining to Riley how he wants to rob the storage unit, at one point there's an over-the-shoulder shot where he says "Totally anonymous... nobody's ever seen any one in there... but, like the shit..." If you look closely, you can tell Trevor is saying something completely different. True, his mouth isn't on-screen the whole time, but his jaw movements and his mouth movements don't match the words at all when they are visible, revealing they altered the dialogue in post.
Audio problem: When Vilmer says "Welcome to mmmyyy world." his mouth says "Welcome to mmmyyy home." (01:02:20)
Audio problem: When Richard is running around the house trying to find Jen near the end, he is heard ferociously breathing and grunting. The breaths and grunts appear to have been dubbed in as Richard's facial and chest movements remain mostly still, which wouldn't happen if he was breathing and grunting that heavily. (01:41:10)
Audio problem: When Oggie races the Turbo interceptor, the engine sounds for his car are from a V8, though his Chrysler Daytona is powered by a turbocharged 4-cylinder.
Audio problem: Simone's scream at the end of her game is the same as one used earlier in the scene. (00:06:00)
Audio problem: Towards the end, IlIana says, "He means thank you," her lips barely even match. And it kind of glitches.
Audio problem: After being told to leave the restaurant, Jung-seok says to Chul-min "You go ahead" and Chul-min proceeds to leave. As Chul-min begins walking away, he is heard sighing in a very heavy and exhausted manner, but his mouth isn't shown moving when it happens. (00:16:22)
Audio problem: When Dale and Tucker are lying on the floor, Dale says he doesn't like fishing, the shot changes to Tucker saying "You don't like.". The shot is from the side of Tucker, yet it's clear that his mouth isn't moving. (00:42:10)
Audio problem: When Montgomery, Parker and Ruth find Lota (The Panther Woman) dead, Montgomery says they should leave her body and escape. Parker turns to him and he makes some kind of objection however there is no audio. (01:08:40)
Audio problem: After Elise notices that Ted Garza owns a lot of her family's old belongings still, he gives an explanation about why he held onto it. In the wideshot where he's in the background, if you pay attention, much of what he says doesn't quite match his lip movements, revealing the dialogue was slightly rewritten and rerecorded in post.
