Created and written by Nat Saunders (Trollied) and James Serafinowicz (The Mark Steel Lectures), Sky Atlantic’s Sick Note is a six-part comedy about how desperate a person’s actions can become when a lie starts to spiral out of control. Harry Potter‘s Rupert Grint, Nick Frost (Shaun Of The Dead) and Don Johnson are starring in the King Bert production. An ealy 2017 airdate is planned.

Principal photography is now underway on the story of Daniel Glass (Grint), a compulsive liar, who’s stuck in a failing relationship and a dead-end job under the thumb of his irrepressible boss Kenny West (Johnson). When he’s diagnosed with cancer, everyone starts to treat him better, suddenly giving him a new lust for life. But then he finds out he was misdiagnosed by the most incompetent oncologist on Earth, Dr Ian Glennis (Frost). When he decides to keep the new information to himself, the lie spirals out of control and both Daniel and Dr Glennis must attempt to prevent the truth from getting out.

Johnson is next starring in feature Vengeance: A Love Story with Nicolas Cage and Deborah Kara Unger. He was last on television in ABC’s Blood And Oil. Grint appeared in 2015 comedy Moonwalkers with Ron Perlman; and frequent Simon Pegg collaborator Frost recently reprised his role as Nion in The Huntsman: Winter’s War.

King Bert was founded by producer Jo Sargent and writer performers David Walliams and Miranda Hart. Sargent (Absolutely Fabulous) is exec producing Sick Note. International distribution for the series will be handled by Sky Vision.
