The Grand Duke is the secondary antagonist of the 2015 live action film Cinderella, based on the 1950 Disney animated film of the same name. Though originally seen in the 1950 film and its sequels as a hero, he is shown having a far more sinister and antagonistic role, secretly working with Lady Tremaine. His transformation into a villain is similar to King Stefan's ironic transformation into a villain.
He was portrayed by Stellan Skarsgård, who also played Viktor Tupolev in The Hunt for Red October, Jim Whitlock in Deep Blue Sea, Terry Glass in The Glass House, King Cerdic in King Arthur and Martin Vanger in the 2011 adaptation of The Girl With the Dragon Tattoo, and Baron Vladimir Harkonnen in the 2021 adaptation of Dune.
