Audio problem: When William reveals himself as the killer, he asks Zeke to be his partner. When Zeke says "I'm in," in a wide-shot, if you look closely, his mouth doesn't move, revealing the line was added in post.
Audio problem: When Zeke is introduced and talking about Forrest Gump, he says the line "He beat China in ping-pong!" But if you look close, his mouth movements don't match the line. The same thing happens later in the scene when he mutters "f**k outta here, man."
Audio problem: During the final test, at one point Marcus says "Shoot this piece of s**t Ezekiel, now." In the first shot, it's clear he's saying something entirely different as his mouth movements don't match the dialogue. The scene then cuts to a closeup mid-line, and the closeup does match... but the first shot doesn't match in the slightest.
