Audio problem: After Captain Lasard delivers his inspiring speech to "Nail these punks," one of the cops stands up and yells "Let's kick ass." even though his lips aren't moving.
Suggested correction: Looked like his lips were moving to me.
They weren't moving. He had a big smile on his face but for him to say, "Let's kick ass." would be impossible without his lips making the necessary movements to say it or with an enormous smile.
I just watched this movie and his lips WERE moving.
I've seen the scene and the mistake is valid. His mouth doesn't move in any significant way for him to say what is dubbed over. His lips barely move as if he simply took a breath.
