Zac Efron is undoubtedly one of Hollywood's most shapeshifting actors, from a 00s Disney star to a Baywatch hunk, and even a notorious serial killer. With his catalogue of popular roles over the last two decades, the 39-year-old has gone above and beyond, transforming for the screen.
While Zac has solidified himself as a Hollywood heartthrob, thanks to his chiselled features and equally chiselled six-pack (and for wooing us all in High School Musical), he's embraced some very different looks and impressively still kept his charisma. In interviews, Zac has stated that "it's fun to be able to give your absolute all" to a role and, for the likes of Iron Claw, where he learned wrestling, he goes the whole way.
