Stephen Graham has issued a ‘profound’ warning to parents about the detrimental impacts of the internet after his Netflix drama Adolescence. The one-shot drama follows the fallout after 13-year-old boy Jamie, played by newcomer Owen Cooper, is accused of murdering a girl in his class.

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."
