MCU: 10 Fascinating Facts Behind Guardians Of The Galaxy (2014)
7. Vin Diesel Recorded 'I Am Groot' In Several Languages And Over 1,000 Times
You might think that Vin Diesel had one of the easiest jobs in the world as Groot, given the only lined he needed to say was 'I am Groot' (well, with a 'We are Groot' thrown in for good measure).
Lest you think that Vin Diesel is not a serious actor who takes this sh*t extremely seriously, however, he went above and beyond in the recording booth. The actor reckons he recorded around 1,000 different versions of the line for the film, ensuring there was a wide range of options and emotions that could be applied.
It didn't stop there, however, as Big Vin also recorded the line for a number of the foreign language releases too, including Russian, Mandarin, Spanish, Portuguese, German, and French, so that everyone around the world could get the full Groot experience.
