Doll & Em: The friendship behind the programme

18 February 2014 Last updated at 00:18 GMT

They have known each other since childhood, but it has taken years for actresses Emily Mortimer and Dolly Wells to get a much talked about joint project off the ground.

Aptly called Doll & Em, the six-part comedy is a British production set in Los Angeles and tells the story of a successful actress who hires her best friend as her personal assistant.

But just how true to life is the pair's creation?

Doll & Em premieres 18 February at 10pm on Sky Living.
