We’ve known for a few years that anytime we hear Groot (Vin Diesel) speak, he’s legitimately communicating with the other members of the Guardians of the Galaxy. Even though the audience always hears “I am Groot,” Guardians filmmaker James Gunn writes out the exact words Groot says in special versions of the script that Diesel receives. Now that one viral video about the topic is going around social media, Gunn himself has stepped in to confirm what is and isn’t accurate. As it turns out, the video is generally fairly accurate.

This video is going around with the “actual” translations of Groot lines from the script (which, yes, I always have). The last one “Dad” is correct (because I’ve shared this before). The others are close, good guesses, but not exact. Still good work! pic.twitter.com/CX532X4vPk

Yes Vin has his own script with what Groot is saying. He works really hard at getting the meaning of each line as well as he can. https://t.co/6p3m851QN7
