James Gunn has announced that principal photography has officially begun for Guardians of the Galaxy Vol. 2.

Along with the announcement, Gunn released a teaser image of the film’s core cast: Rocket Raccoon (voice of Bradley Cooper), Drax (Dave Bautista), Groot (voice of Vin Diesel), Star-Lord (Christ Pratt), and Gamora (Zoe Saldana). Groot is apparently still growing out of his “baby Groot” phase.
