A Voldemort laugh. He has his followers, but that’s about it.
Besides that, this Happy Potter character is also one ugly dude, sort of like cinema’s Pinhead. I’d be a cranky fellow if I looked remotely like that! Before coffee doesn’t count, everyone looks like Voldemort before coffee.
To be honest, I’ve seen all the characters, but I have yet to see on Potter film, nor read even a word from any of the books.
