A HARRY Potter star looked worlds away from his hit movie role after switching up his look.
The Blackpool-born actor, 61, sported a lengthy brunette hairstyle and silver bushy beard on-set in Dublin.
David Thewlis played Remus Lupin in the hit flicks based on JK Rowing's novels.
The character actor, who made his film debut in Little Dorrit back in 1987, starred in the entire Harry Potter film franchise from 2004 to 2011.
As his professor character, he was often seen donning a brown blazer, shirt and tie and armed with a wand.
He played the Defence of the Dark Arts professor who later chose Harry to be godfather to his son due to their close bond.
Yet during the Battle of Hogwarts, his wife was slayed by Bellatrix Lestrange.
His brunette hair was poker-straight with a fringe framing his forehead.
Yet for his latest role, The Theory Of Everything star cuts a completely different look.
Gone are the straightened locks for a frizzy, volumous style reaching to his shoulders.
