Audio problem: Throughout the series the engine sound from Walt's Pontiac Aztek sounds like a 4-cylinder engine, but the Aztek was only ever available with a V6.
Audio problem: When Hardison is talking to Carrey, just after he names his price ("30%"), there is a shot from a strange angle in which we hear Hardison talk while his mouth doesn't move at all.
Audio problem: When Gemma is talking to Clay in jail there's a shot "en profil" in which we only see the silhouette of her face. When Clay sits down you can see she's saying something, while the only sound we hear is Clay exhaling.
