Adolescence creator Stephen Graham has shared what he considers the show’s “biggest achievement”.

The star says the special approach to the show from producer Warp Films, co-creator and writer Jack Thorne and director Philip Barantini, meant that he was "the most zen as an actor I've ever been."

Netflix's emotional mini-series Adolescence has become the topic of conversation, following the story of a family whose world is turned upside down overnight.
