30. JAMIE FOXX And RAY CHARLES

Jamie Foxx didn’t just act like Ray Charles in the 2004 biopicRay— hesoundedandlookedexactly like him. With prosthetics, a wig, and months of piano and vocal training (while wearing blindfolds to simulate Charles’ blindness), Foxx became the legendary musician.
The physical and vocal match was so uncanny that Ray Charles himself approved of the casting before his death. Foxx won the Oscar, and the film remains a masterclass in biographical performance.
