Audio problem: When Dr. Wren takes Cal's gun, he says, 'You really are way too trusting', but his mouth movements seem to show him saying something else. It appears to be something along the lines of 'far too trusting,' as opposed to 'way too trusting.' (01:09:30)
Audio problem: Near the end of the film, when we see the Queen's new mutation, the scene opens up by showing all the scientists attached to the wall. Dr. Gediman is rambling on and on about the Queen's 'perfect' mutation. However, it is quite clear he isn't saying any of the words. In fact, from the way his mouth moves, it looks like he's literally saying 'blah blah blah, blah blah blah'. (01:27:05)
Audio problem: In the nest, the creepy guy talking does not sync his words with his lips half the time.
Answer: In Alien 3, Ripley discovers there was an Alien queen embryo growing inside her, so she chose to kill herself. By cloning her, scientist were hoping the Alien queen embryo she had in her at the time of her death would also become cloned, which finally happen after the 8th try. This is also why the Alien queen they extracted from Ripley has some human traits.
