Actor Vin Diesel has once again hinted at a new Guardians of the Galaxy movie focused on Groot, sharing details about his work on a project titled The Arbor King. The actor, who voices Groot in the Marvel Cinematic Universe (MCU) films directed by James Gunn, recently posted AI-generated artwork showing Groot facing off against the Hulk, teasing his enthusiasm for the story’s development.
Diesel explained that he has been deeply involved in writing this new Groot story, describing it as a long-awaited tale about Groot’s return to Planet X. He also highlighted the emotional connection he has with the character and those who have grown to love Groot through the franchise.
Insights from Vin Diesel on the New Groot Narrative
Vin Diesel shared his inspiration behind the Groot project, comparing it to cherished storytelling traditions:
I was always fascinated by the origins of how the Hobbit came to be… the idea that it started as a story a father would tell his children around a campfire,
he posted.
He added,
As you know, I have been deep in development and writing on so many of the characters I have grown a bond with. Just recently, I read to my family, The Arbor King… the long awaited story of Groot’s return to Planet X…

Diesel passionately affirmed the significance of this story to fans and younger audiences alike:
There’s movies the world wants, my incredible fans want and of course the ones the kids want. We are Groot!
Earlier Indications of a Solo Groot Project from Diesel
This is not the first occasion that Vin Diesel has stirred excitement about a solo Groot movie. In July, he posted—and swiftly deleted—a message announcing the completion of the Groot sequel for Disney, again naming it The Arbor King. He also referred to Planet X as a film that Marvel fans highly anticipate, describing it as the story where Groot returns home.
One of Diesel’s posts read:
So much to be excited about… Finally finished the Groot sequel for our friends at Disney… The Arbor King. You all know the other films in process or upcoming, but something about the continuation of that beloved floral colossus just feels different. Haha. Blessed.
Marvel’s Current Position on a Groot Standalone Film
Despite Vin Diesel’s enthusiasm, Marvel Studios has not officially announced any plans for a Groot solo movie titled The Arbor King or Planet X. The most direct Groot-related content released so far includes the I Am Groot animated shorts available on Disney+. There are also no announcements regarding the next Guardians of the Galaxy film, and cast members have not been confirmed for the upcoming Avengers: Doomsday.
Meanwhile, fellow Guardians actor Dave Bautista has publicly expressed interest in a movie centered on his character Drax but revealed Marvel declined the idea, adding a layer of uncertainty around solo projects for individual Guardians.
Diesel has a history of leveraging social media to generate buzz and push projects forward, as he did with Riddick 4, which he promoted extensively for years before it entered production. Whether The Arbor King will materialize as an official Marvel project or remains an idea Diesel champions to engage fans remains uncertain, but his dedication indicates a powerful desire to see the story come to life.
