Ewan McGregor was spotted looking unrecognisable as he left a salon on his motorbike in Los Angeles yesterday.
The 42-year-old Beginners actor, who recently confirmed he is "totally up" for reprising his role in a Trainspotting sequel, was photographed sporting jet black hair instead of his usual light auburn colour.
The star also revealed a rather fetching handlebar moustache and a touch of a goatee as he hopped on his motorbike.
It's believed that his radical transformation is for his upcoming role in Natalie Portman's Western Jane Got a Gun, having replaced Bradley Cooper after the latter pulled out due to his hectic schedule.
Fellow Hollywood actor Christian Bale was also spotted debuting a dramatic new look when he was photographed with a shaved head while touching down in LAX with his family.
The 39-year-old actor has transformed his image to star in David O Russell's crime drama American Hustle.
