With his long face, set apart eyes and pointed chin, 16-year-old Tyler Michell is a dead-ringer (if you squint, in dark light) of the Oscar-nominated The Imitation Game star.
In the last few months, Tyler has become a pin-up for girls from as far away as Russia and the Philippines because of his resemblance to the Sherlock star.
At home in Norwich, he gets stopped in the street and asked about 'his' latest movies.
Tyler told the Mail: "It started out as a joke - my close friends and family would tease me and say I looked like Benedict Cumberbatch.
"I guess I look like him a little - but I really didn't take it seriously. Then people would come up to me at school and say 'Wow you really look like Sherlock.'
"Suddenly people started adding me on Facebook, Twitter, Instagram, and I got more and more friends and followers.
"I get girls from Brazil saying the want to meet me in the UK which is crazy as I'm just a teenage boy sitting at home.
"Now people are messaging me and saying I should have won the Oscar (which Eddie Redmayne received for Best Actor).
"I was shocked Benedict didn't win. This might be biased but I thought he was the best nomination.
"Even though he lost, it hasn't stopped the attention I get. I still get inundated with people messaging me on social media saying I look like him or that they love my work."
Despite the attention, Tyler says he can't see the similarity with Benedict, who is expecting his first child with new wife Sophie Hunter.
Tyler tells fans who stop him he's not Benedict, but still happily offers them his signature.
He said: "A couple of people have suggested me being a 'Teenlock' - a young version of the detective. I'd love that but I don't think it will happen."
Tyler's mum Nicola Alderton said: "When one of his friends pointed it out we were gobsmacked.
"It could be quite surreal having a Hollywood superstar lookalike in the house, but he's just our Tyler."
