Starring Blake Harrison and Richard Gadd

The Inbetweeners star Blake Harrison and stand-up Richard Gadd are to star in a new E4 comedy-drama set in parallel universes.

In Tripped, Harrison plays Danny, an average 24-year-old who has been friends with stoner Milo, played by newcomer George Webster, since they were kids. But then Danny decides it's time to settle down and marry long-term girlfriend Kate (played by Georgina Campbell), whereas Milo continues to focus on getting high.

Throughout the series Danny and Milo trip into various hallucinogen-fuelled parallel worlds where they encounter different versions of themselves, all the time being chased by a dangerous assassin played by Gadd

Tripped was commissioned following an original pilot by stand-up-turned-scriptwriter Jamie Mathieson, entitled Alt. The four new hour-long episodes written and co-created by Harry and Jack Williams, who wrote BBC One's The Missing.

Beth Willis, deputy head of drama at Channel 4, said: 'Jack and Harry's scripts for Tripped are a breathless and brilliantly funny ride – and we're so thrilled to have Blake Harrison back at Channel 4, playing Danny and Danny and Danny.'

Harrison added: 'It's always frustrating when good actors make me look bad but on this show I get to have a lot of scenes with myself, so I should look all right. Also they've let me have a sword so if anyone brings me a cold steak I can go full medieval Clarkson on their ass!'

The series is being made by Mammoth Screen, whose current productions include BBC One's Poldark, produced by James Dean from This Is Jinsy, and directed by Jamie Stone of The Village.

Tripped goes into production this week and will air on E4 later in the year.

In December, Chortle reported on another series Gadd is working on for Channel 4, based on his trilogy of stand-up shows that concludes at this year's Edinburgh Fringe.
