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.

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.
