Vin Diesel On Groot & Rocket's 'Guardians Of The Galaxy' Friendship: They 'Love Each Other'

Vin Diesel and Bradley Cooper might have accomplished a big screen impossible – making the friendship of a talking raccoon and a barely talking (but walking!) alien tree believable and moving.

Vin sat down with Access Hollywood's Liz Hernandez and chatted about blasting into the Marvel Universe as "Guardians Of The Galaxy's" Groot – who only says one line, "I am Groot."

"They didn't computerize my voice," the actor said, explaining what you hear in the Marvel movie is not altered. "It was just me."

Vin was blown away with how director James Gunn created such chemistry between Groot and Bradley's gun-wielding foul-mouth talking raccoon – and the actors never even worked in the recording studio together.

"I saw the movie and I was just like, I love these two and these two love each other and they have a real relationship and that's exciting and I want more. Again, that's a testament to both the CGI guys that created such a framework for my character and to James Gunn for protecting that chemistry and assisting that chemistry. Because it really does come off in the film," Vin said.

The big screen star's kids helped him decide to take the one-line character.

"I don't think [Marvel] thought that I would do the role, but when I got it, when I got the concept art, I went home and I showed it to my family and I asked them, 'Which character do you think they want daddy to play?' and the kids pointed to the tree and there was something in that moment where I went, 'This is going to tap into people in a way that I can't even explain,'" he recalled. "Jump cut to [my kids] seeing the movie, loving the movie, imitating Groot and Rocket and everybody…my kids now look at trees differently."

"Guardians of the Galaxy," which also stars Chris Pratt, Zoe Saldana, Dave Bautista, Djimon Hounsou, Michael Rooker, Karen Gillan, Benicio Del Toro, Josh Brolin, Glenn Close and John C. Reilly, opens on August 1.
