Vin Diesel Grows Long Beard & Mohawk For 'The Last Witch Hunter'

He's an action star known for his striking muscular physique and smooth bald head. But for his latest role, Riddick star, Vin Diesel is letting himself get into a very hairy situation. The 47-year-old is nearly unrecognisable as he sports a shaved brown mane and a long bushy beard for the supernatural adventure film"The Last Witch Hunter. While he won over audiences as the voice of sentient tree Groot in the summer blockbuster Guardians Of The Galaxy, this time the burly star is masking his appearance without the help of CGI.

In the new stills from the set, Vin has a mohawk type hairstyle and an unruly brown beard long enough to braid at the ends. The star looks pensively up to the sky as he rests his head on his fist while decked out in a dirty lace-up shirt. In another snap (above), he wears a more menacing grin while cloaked in a vest made from the fur of an animal.

The film deals with an immortal witch hunter named Kaldur (Diesel) who has to come between two covens in order to stop a horrific plague that threatens to destroy humanity. Joining him onscreen are Game Of Thrones star Rose Leslie, Elijah Wood and Michael Caine.

While currently in production, The Last Witch Hunter is set to hit theatres in Fall 2015.
