Once forever typecast as Dudley Dursley in Harry Potter, Harry Melling has made a dramatic, unrecognizable turn—literally and figuratively—at the 2025 Cannes Film Festival.

Directed by Chad Hartigan and written by Simpsons alum Ethan Ogilby, The Threesome follows the awkward, chaotic, and hilariously emotional fallout of a spontaneous romantic entanglement. Premiering at South by Southwest and arriving in theaters September 5, 2025, it stars Zoey Deutch, Jonah Hauer‑King, Ruby Cruz, with comedic turns from Jaboukie Young‑White and more.
