Transformers (Lost episode) - S1-E7
Character mistake: When Donnie turns to the cameraman, Carl, and asks if he liked the film they just made, he responds in a normal American accent. Carl has been established in the series as German with a thick German accent, and the actor playing him, Rob, either forgot to use the accent or just didn't at that moment with them forgetting to change the audio in post.
