In Marvel Studios’ “Guardians of the Galaxy Vol. 2,” Vin Diesel returns to voice Groot, an extremely humanoid tree with an extremely limited vocabulary. In fact GROOT is one of the most popular characters in the Guardians universe thanks to his iconic ' I Am Groot'. Fans often wonder what attracted Vin Diesel to the part of Groot and the actor is happy to explain! "I went to meet with Kevin Feige for a couple hours to talk. A couple of weeks later, Marvel sent over a book of concept art and they had this crazy idea that kind of played to the Iron Giant character I played in the beginning of my career. And what sealed the deal for me was when I opened up the giant book of concept art and fell in love with the character Groot. I asked my son which character he thought Daddy should play, and my son, Vincent, who was three at the time, pointed to the tree. And something about that made me feel like it was going to be the perfect match." he says For Diesel, there is much to love about the quirky character. “I loved the gentle giant aspect of Groot,” he says. “I loved how enigmatic the character is. He's been labeled the most interesting character in the Marvel universe because he’s so unique and so different.
