Actor Idris Elba and his doll look-a-like

He is a star of stage and screen, and now you could bring him home!

It's the doll version of Idris Elba! Really??

Emperis, a doll designer, created the suave looking doll apparently in the likeness of the actor, famous for being in the Marvel movies.

Style this: Harry and his doll double

Do you remember a little band called One Direction?

One figure in particular stood out as being a bit different from the rest.

Boxer Nicola Adams and her Barbie doll - who do you think would win in a fight?

At first glance, this Nicola Adams doll would appear to be a pretty good replica of the sports star?

The Barbie doll was released earlier this year to celebrate International Women's Day and other famous women such as Frida Kahlo and Amelia Earhart.

And while many were pleased to see the Olympic gold medallist represented, some pointed out that her body didn't quite match that of the boxer's.

While they managed to capture her hair and some of her style, where are the muscles in those arms??
