The Guardians of the Galaxy Holiday Special was an absolute delight, and proof Marvel Studios' "Special Presentations" are among the best ideas they've had in this Multiverse Saga era of storytelling.
With the filmmaker gearing up to make the leap to DC Studios as its new co-CEO alongside producer Peter Safran, he won't be returning to the MCU for any further projects after next May's Guardians of the Galaxy Vol. 3. As a result, the only Holiday Specials we're likely to get from him are those set in the DCU (The King Shark Holiday Special, anyone?).
Over the past few days, Gunn has been sharing plenty of insights into his MCU return on social media, including the fact he had a secret role in the Christmastime caper.
There's been a lot of confusion over how Groot was brought to life in The Guardians of the Galaxy Holiday Special, with many left convinced it was actually a practical costume instead of VFX. Gunn has debunked that, but confirms he once again provided the motion reference for Groot's dancing.
He did the same for Guardians of the Galaxy's mid-credits scene and again in the sequel's standout opening dance number.
Gunn has also revealing this Groot is the Young Adult version of the character, naming him "Swoll Groot." Vin Diesel has previously said we'll see "Alpha Groot" in the threequel, though the director would later go some way in dismissing that (the Fast & Furious star making bold, hard-to-believe claims about his place in the MCU has become the norm).
