Leonardo DiCaprio is set to produce a new film titled Howl, and he will be joined by environmental activist Jane Goodall.

The film’s story will center on an abandoned family dog and a young wolf, and it will be told from the animals’ perspective.

The story is set against the backdrop of a harsh winter, and it will follow Harry, “a family dog who is inadvertently left home alone and whose owners then die in an accident.”

“Harry goes through a rollercoaster survival ride that brings him into contact with a wolf. The pair must overcome their mutual fear and suspicion, and ultimately they develop a close bond.”

While the story will focus on the animals, there will be some human characters that appear as well, but that casting has yet to be announced.

It’s explained that this is not an environment film, but the creative team behind is looking to give moviegoers a transformative view of the natural world.

E. Elias Merhige (Shadow of the Vampire) will direct the movie, and Christopher Monger (Temple Grandin) has written the screenplay.

Goodall said in a statement: “Howl will not only be an enjoyable and entertaining experience but will also help change perceptions of the ‘big bad wolf,’ which has been hunted to extinction in many areas of the world and is threatened and endangered in many others.”

She added: “I hope we can make people understand their need to live alongside us and show these sacred creatures for what they are.”

Executive producer Jennifer Davisson said: “Along with our good friend Jane Goodall, we were thrilled to board such a project as Howl that will stimulate such curiosity and enjoyment from all ages around the world.”

She continued: “We hope this film encourages people to understand and appreciate the inextricable relationship between us humans and the natural wildlife that surrounds us.”

Director Merhige said Howl is a tale that will ask us to look beyond our human experience: “It is a daring and truly distinctive project and I’m incredibly excited to begin work with our amazing animal stars.”

Producer Richard Johns shared: “Their mutual love of wolves as a symbol of the wild and their authentic passion and commitment to telling inspiring and powerful stories about nature, the environment and sustainability will help elevate our film and ensure it gets to be seen by the widest possible audience.”

Producer Fabrice Lambot shared: “With Promethean, we share an ambition to create a once-in-a-lifetime global film and nature event that appeals to audiences of all ages, and we are already exploring some interesting ancillary projects as part of a potential Howl universe.”

Howl is now shooting with the film expected to be released in early 2026.
