Harry Potter’s Ralph Fiennes Offers Funny Wardrobe Advice to Reboot’s Voldemort

During an interview withEntertainment Tonighton TikTok, Fiennes was asked if he had any advice for the next Voldemort actor stepping into the franchise. “My advice is make sure you can handle the long, flowing robes and don’t trip over them,” Fiennes said with a straight face, and continued with, “Practice your long, flowing robe walk.” The actor then reflected on his time as Voldemort wearing tights within a one-piece suit, as well as an “uncomfortable” gusset that kept lowering as the shooting day went on. Fiennes previously showed interest in picking up the role again, as well asHero Fiennes-Tiffin’s recent eagerness to return to Voldemort in the reboot, but since HBO has locked in an entirely new cast so far, a fresh-faced actor is pretty much guaranteed.

Serving as the main antagonist in the franchise, Voldemort, being an anagram for the wizard’s real name Tom Marvolo Riddle, was the culprit behind Harry’s murdered parents and the trademark lightning bolt scar on his forehead.Voldemort originally had a terrifying real formthat never made it into the live-action films, but the noseless villain managed to cement himself as an ultimate antagonist in pop culture history with Fiennes at the helm, regardless.
