Corrected entry: In the scene near the end of the film where Harry tricks Lucius Malfoy into freeing Dobby, Malfoy is understandably enraged. He pulls out his wand and snarls "You've lost me my servant, boy." and then begins to shout "Avada....." before Dobby interrupts with "You shall not harm Harry Potter." Readers of the books will recognize this as the first word of "Avada Kedavra", the Unforgivable Curse which results in the instant death of the victim. An interesting way to show just how angry Malfoy was. It was also quite reckless. If anyone found out he did it, he would spend the rest of his life in Azkaban (until Harry Potter and the Order of the Pheonix anyway) if it was ever discovered he did it. And of course Dobby would have been a witness, unless Lucius killed him too. DVD subtitles actually show that he is starting to say "Vera-", but that doesn't match his mouth movements.

Correction: On the contrary, his mouth does match the words if he was rolling his "r" in the word "vera-" as I suspect.
