He is best known as this generation's incarnation of Sherlock Holmes and he wouldn't be the eccentric detective without his head of curly dark hair.
But it seems Benedict Cumberbatch has parted with his trademark look to film new Second World War drama The Imitation Game in London.
The 37-year-old actor had his hair parted harshly to one side and slicked down in a straight style.
He also appeared to be sporting a lighter a hue than the raven locks viewers of Sherlock will be familiar with but the actor is naturally fair.
The Public School-educated actor wore a grey dog-tooth jacket and shirt and tie to shoot the scenes in which he portrays Alan Turing, a real- life mathematician who helped to crack the enigma code during the war against Nazi Germany.
Turing was later tried for being a homosexual in homophobic 1950s Britain and is believed to have later committed suicide.
