Audio problem: During the speech where Al tells Sam to quit (to force Chewie to play), Sam says he can't quit but his mouth doesn't move for a couple seconds after the words start playing.
Audio problem: In the opening title sequence towards the end, Link says "For you, Princess, anything." After he says this, he instantly opens his mouth again in a continued talking motion. But he is not saying anything. In a cartoon such as this, especially from this era, they wouldn't go through the trouble of animating just a breath after a speaking line, or even just a smile like that. It is extra animation for speaking that is not happening. (00:00:25)
