Even after being delayed for quite some time, we still know very little about the upcoming Guardians of the Galaxy Vol. 3‘s plot. We only know that director James Gunn will part ways with the franchise once he finishes his trilogy. Now, it seems that Vin Diesel, the voice of Groot, has confirmed his character’s homeworld will appear in the Marvel Cinematic Universe at some point. He revealed the news in a recent video interview with ComicBook’s Brandon Davis, which he shared on Twitter. He references the plot development by pointing out it’s a story Marvel Studios CEO Kevin Feige is quite excited about in an upcoming project. However, he doesn’t outright confirm which one it might be, as the character is slated to appear in next year’s Thor: Love and Thunder, the Disney+ series I Am Groot, and, of course, Guardians of the Galaxy‘s third entry. Going by the interview and Davis‘s tweet, it seems likely he is referencing the next Guardians film.

In the comics, Planet X is the homeworld of Groot’s species, the Flora Colossi. The location was referenced in the first Guardians of the Galaxy film when it was listed on the Nova Corps’ prisoner profile for Groot. Interestingly, the planet was referred to as “Taluhnia” in the initial trailer for the movie, before being changed in the final product. If Diesel was indeed teasing a plot point for the next Guardians, it’s possible Gunn goes back to this alternate name as a way of branching out and exploring the planet’s culture. After all, the filmmaker does have a history of changing his character’s comic origins. Sadly, it may be a while until we know for sure.
