Actors Dominic McLaughlin and Nick Frost lead the cast of the award-winning family comedy feature film Grow, which officially premiered for streaming on Peacock in the United States on October 1, 2026. The release arrives just months before both actors make their highly anticipated debuts in HBO’s upcoming Harry Potter television series, where McLaughlin stars as Harry Potter and Frost portrays Rubeus Hagrid.
The 107-minute British film was produced by Double Nickel Entertainment in association with Sky, Orogen Entertainment, and Blazing Griffin. Directed by John McPhail from a screenplay written by Nick Guthe, Ruth Fletcher, and Christos N. Gage, Grow blends heartfelt family dynamics with small-town eccentricities and competitive agriculture.
Plot and Cast Details
The story centers on Dinah Little, a no-nonsense, curmudgeonly farmer residing in a self-proclaimed pumpkin capital, played by Golda Rosheuvel, who is known for Bridgerton. Dinah reluctantly takes in her abandoned niece, Charlie, portrayed by Priya-Rose Brookwell, and puts her to work on the farm.
Charlie soon discovers a special, magical gift for connecting with plants. This unique talent aids her as she enters the town’s annual giant pumpkin-growing competition, which features wild stunts, eccentric locals, and fierce rivalries. Dominic McLaughlin stars as Oliver Gregory, Charlie’s sensitive best friend, while Nick Frost plays Arlo, a local pumpkin grower.
The supporting cast also features Joe Wilkinson, Tim McInnerny, Jane Horrocks, Kathryn Drysdale, Fisayo Akinade, Sharon Rooney, Jeremy Swift, and Alan Carr.

Connection to the Upcoming HBO Harry Potter Series
