Audio problem: When Batman meets Catwoman in the tunnel to meet Bane, her lips don't move when she talks, then her lips move when she is not talking.
Audio problem: After Bruce escapes from the pit, he and Selina talk under a bridge. Bruce says "I admit I was a little let down" but his lips aren't moving. (02:01:17)
