The things they say:

“There’s an old actor’s legend in New York where people talk about how Robert De Niro… wouldn’t know his character until he found his shoes… So I was thinking of a way to become this flora colossus, this seven-and-a-half foot… tree… I got these jumping stilts that made me seven-and-a-half feet tall and I would wear them into the recording booth and for some reason, my body composition started to feel kind of like a tree.” Actor Vin Diesel on using stilts to help him get into character as Groot in the new Guardians Of The Galaxy film.
