dominic mclaughlin is already on screen with Nick Frost in Grow, which began streaming on Peacock in the United States on October 1. The pairing lands two months before HBO's Harry Potter series is due to introduce them in their new roles. For viewers tracking the cast before that shift, Grow is the first chance to see how the two play off each other in front of a camera.
Grow on Peacock
Grow brings McLaughlin and Frost into the same story now, not later. Golda Rosheuvel leads the cast as Dinah Little, while Priya-Rose Brookwell plays Charlie and McLaughlin plays Charlie's friend Oliver Gregory in Grow. Frost appears as local grower Arlo, giving the film a setup that lets audiences size up both actors before Harry Potter and Rubeus Hagrid move into the HBO frame.
October 1 also put the film into the BAFTA Scotland Awards conversation, where it was nominated for Best Feature Film. That nomination gives Grow more than just timing value: it now sits in the awards field at the same moment it becomes a streaming title, which is the kind of crossover that can widen attention beyond the audience already watching for the new Harry Potter cast.
HBO's two-month gap
Two months is the useful number here. Grow arrives first, and HBO's Harry Potter series follows after that with McLaughlin as Harry and Frost as Rubeus Hagrid. The order matters because it turns a family comedy into a preview reel for two roles that carry much heavier franchise expectations.
Nick Frost is stepping into Hagrid after Robbie Coltrane played the Hogwarts gamekeeper across Warner Bros.' eight original movies. That comparison gives the HBO casting a built-in benchmark, while also making Grow a cleaner test of chemistry than a trailer cut or still image ever could.
Charlie, Oliver Gregory, and Arlo
Priya-Rose Brookwell's Charlie keeps the film from becoming a pure casting teaser. With Golda Rosheuvel as Dinah Little and McLaughlin as Oliver Gregory, Grow has a family-comedy structure that lets the new Harry Potter names work inside a separate story rather than a publicity reel.
The sharp read is simple: if you want to judge McLaughlin and Frost as a screen pair before HBO puts them in Hogwarts, this is the window. Grow is now the early sample, and the Harry Potter series is the larger job still to come.
