Sky has confirmed that it has commissioned a new family comedy, Grow, with filming now under way in Scotland.

Set to air on its Sky Cinema channel next year, the film stars Golda Rosheuvel and Priya-Rose Brookwell as farmer Dinah and Charlie, the niece she didn’t know she had.

The broadcaster says: “Grow is the story of Dinah Little, a no nonsense, curmudgeonly farmer with a heart of gold, and Charlie, the unknown and unloved niece Dinah begrudgingly takes in after discovering her in an orphanage.

“Dinah’s farm is in the self-proclaimed ‘Pumpkin Capital of the World’ where the biggest event of the year is a high-stakes cutthroat giant-pumpkin-growing contest where the entire town gets their pumpkin patches ready to compete for a cash prize and pumpkin glory. Charlie has a special bond with plants and, combined with her feisty personality and determination, decides to grow a gigantic pumpkin for the competition, to attempt to win the coveted prize.

“However, Charlie and other pumpkin growers face sabotage and advanced pumpkin technology in the battle of the pumpkin bulge. As she nurtures ‘Peter’, her pumpkin, and sees him grow, so does a bond between Dinah and Charlie.”

It has been written by Nick Guthe, Christos N. Gage, Ruth Fletcher Gage, Mark Huckerby and Nick Ostler.

Nick Frost co-stars as eco-loving pumpkin pundit Arlo, with Jeremy Swift as Mr Gregory, a pumpkin-obsessed mad scientist. Tim McInnerny and Jane Horrocks appear as Lord and Lady Smythe-Gherkin, the town’s reigning pumpkin-growers, whilst Alan Carr plays the MC.

Supporting cast members include Joe Wilkinson as the hapless Boris Mudd; Kathryn Drysdale as Charlie’s mum, Polly Little; Fisayo Akinade as lab assistant Kevin; and Sharon Rooney as Sharon, who runs the orphanage.

Director John McPhail says: “Grow is a joyous comedy about growth, nurturing and family. Set in a world of pumpkin obsessed, madcap characters but grounded in real relationships, it’s a film the whole family can enjoy.”

Andrew Orr, Head of Original Film for Sky, adds: “Across the Sky Cinema offering, we strive to deliver best-in-class content, including brilliant family titles from fantastic talent. Grow has a stand-out cast of best of British actors, and it’s shaping up to be an unmissable treat for audiences of all ages. We look forward to introducing families to the world of Dinah and Charlie as they tackle personality clashes and pumpkin rivalry, as an unlikely but ultimately charming duo.”

Adam Richman, Jenette Kahn and Joe Capotorto of production company Double Nickel Entertainment say: “We are thrilled to be working with our partners at Sky and Orogen Entertainment on this classic seasonal perennial, which audiences will love year in and year out.

“John McPhail has realised the absolute best and magical version of Grow – a funny, heart-warming, and forward-looking film. Led by the incomparable Golda Rosheuvel and the hilarious Nick Frost and Jeremy Swift, the movie will delight audiences across the globe with its humour, messages of inclusion and sensitivity to nature.”
