Vin Diesel thinks a Rocket and Groot "Guardians of the Galaxy" spinoff would be "huge," and we can't disagree.

The actor, who voices the lovable tree creature, just told USA Today, "James Gunn has always wanted a Rocket and Groot movie. And I know that Disney is very much into being successful. And the most successful poster in Disney's future is the poster that has 'Groot vs. Hulk.' ... [The world] cannot wait to see it."

However, Gunn (who wrote and directed both "GOTG" movies) seemed to cast doubt on that happening. "Vin has a lot of ideas. I don't know where he comes up with these things! I love Vin," he told USA Today at "Guardians of the Galaxy Vol. 2"s premiere.

So is a spinoff just a figment of Diesel's imagination or is Gunn simply being ultra-coy?

There is a "Marvel's Guardians of the Galaxy" TV series.

Until that spinoff is officially announced, we'll just be over here playing with our Groot and Rocket action figures, thanks!
