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."

Adolescence has recently arrived on Netflix and Stephen Graham stars as Eddie Miller, the distraught father of a 13-year-old boy accused of murder. Owen Cooper plays Jamie, who stands accused of the heinous crime.
