Sky 1 adds Sick Note to its growing line-up of post-watershed comedies set to air in a new 10pm comedy slot this autumn. And Lindsay Lohan (Mean Girls) will join Rupert Grint (Harry Potter Series) and Nick Frost (Paul) for series two, which is currently shooting in the UK.

Sick Note follows the story of Daniel Glass (Rupert Grint), a compulsive liar stuck in a failing relationship and dead-end insurance job, under the thumb of irrepressible boss Kenny West (Don Johnson). Just when things couldn’t get any worse, Daniel is wrongly diagnosed with a terminal illness by his incompetent doctor Ian Glennis (Nick Frost). When the error comes to light, Dr Glennis convinces Daniel to hide the truth of his misdiagnosis from colleagues, friends and family in a lie that spirals wildly out of control.

The first series of Sick Note will air on Sky 1 and TV streaming service NOW TV this autumn. Sky 1 is now the home of original comedy on Sky and Sick Note is one of a host of edgier, grown-up comedies commissioned for the channel’s 10pm slot. Other shows in the autumn line-up include Bliss, a comedy starring Stephen Mangan and Heather Graham from Emmy award-winning director David Cross, and Bounty Hunters, a new action-comedy from Jack Whitehall and Freddy Syborn.

Commenting on the commission, Sky’s Head of Comedy Jon Mountague said: “One lie leads to the next in this unsettlingly brilliant comedy that will hook viewers in and have them on the very edge of their seats. Filming for series two is already under way and we’re delighted to confirm Lindsay Lohan will be joining Rupert and Nick in this stellar comedy cast.”

Series two will pick up from the end of the first, with Lindsay Lohan taking on the role of Katerina West, the daughter of Daniel’s boss.

Produced by British production company King Bert, founded by renowned producer Jo Sargent and writer performers David Walliams and Miranda Hart, Sick Note is created and written by Nat Saunders and James Serafinowicz and directed by the BAFTA-winning Matt Lipsey (Little Britain, Psychoville). It is produced by Sarah Fraser and exec produced by Jo Sargent, who commented: “We are thrilled to be making a second series of this nail-biting comedy and very excited to be welcoming the extraordinary talents of Lindsay Lohan to our all-star cast.
