Vin Diesel better brush up on his foreign languages, because according to the actor himself he'll be going through a slew of them for Guardians of the Galaxy vol. 2. While talking to Jimmy Fallon, he of the Trump hair ruffling, on The Tonight Show, talk turned to the upcoming sequel. While Diesel's character Groot is reportedly a little baby sapling for most if not all of the movie, the gruffly voiced actor is still providing his vocals.

While Diesel did Groot's famous one liner "I Am Groot" in six different languages for The Tonight Show in his last appearance, he might do as many as 16 for the film itself this time around, and it's all Fallon's fault.

"Because it went viral, James Gunn now wants to take it from six languages to sixteen," Diesel said. "Now he wants to do sixteen languages."

Diesel then demonstrated the line in Korean, which sounds roughly like "Cho Noon Groot Ee-ay-oh." Apologies to any native speakers of that language, on behalf of Diesel.

The actor also talked about dressing up with co-star Zoe Saldana for Halloween, as the two both have babies at the moment, and they took their kids out trick-or-treating together.

Diesel has quite a bit coming out in 2017, with xXx: Return of Xander Cage and Fast 8 hitting along with Guardians 2, reprising roles in both those franchises, which he also guides as a producer. Groot and the rest of the Guardians are expected to appear in Avengers: Infinity War as well, culminating the full Marvel Cinematic Universe output so far. While only saying a total of 5 words in the first movie, Groot (and Vin Diesel's performance) was a breakout from the film, with his various intonations lending a shocking amount of emotional context to the giant talking tree.

Guardians of the Galaxy vol. 2 hits theaters the first weekend of May 2017, with Doctor Strange hitting first in November from Marvel Studios.
