Zooey Deschanel and Charlie Cox share the screen with an adorable, scene-stealing, very good boy in Merv. The good boy is the titular character and the plot involves getting his happy vibe back.
The romantic comedy also stars Chris Redd and Patricia Heaton. Merv premieres on Prime Video on December 10, 2025.
“When their beloved dog Merv loses his spark after their split, Anna (Deschanel) and Russ (Cox) are forced into the world’s most awkward co-parenting arrangement. Hoping to shake Merv out of his funk, Russ takes him to Florida for a much-needed getaway—only for Anna to show up unexpectedly,” reads Prime Video’s synopsis. “As Merv slowly gets his groove back, turns out fixing their dog’s broken heart may lead to a few sparks of their own.”
Jessica Swale (Summerland) directs from a screenplay by Dane Clark and Linsey Stewart. Matthew Baer and Roma Downey serve as producers.
