I’m really angry that, in the movie adaptation, Polyjuice potion did not change voice.
1. It’s EXTRA editing and EXTRA work they didn’t need.
2. The actor who plated Albert Runcorn apparently had the most badass voice that now we’ll never get to hear say badass lines.
3. CONTINUITY ERROR. Barty Crouch’s voice doesn’t come out of Moody’s body. Maybe he’s just a more skilled wizard and is more adept at potions?
4. When you change things, avid book readers get sad.
