Fiennes's nephew, Hero Fiennes-Tiffin, portrayed Tom Riddle
as a child in Harry Potter and the Half-Blood Prince.
The primary cast, all of whom were German besides Fiennes, Olin and Winslet,
also decided to emulate Kross's accent since he had just learned English for the film.
Roald Amundsen, Ranulph Fiennes and other arctic explorers might be
surprised to learn that, when they visited the North Pole, they were actually standing on the south pole of a magnet.
Turns out, although they did about 25 takes of the scene, this take with the hug
wasn't in the script, and was really just something Ralph Fiennes(Voldemort) did as a one-off,
but it somehow ended up making the final cut.
