The opening credits sequence for Guardians of the Galaxy Vol. 2 set the tone for what was to come in the rest of the two hour blockbuster. 

In the sequence, Baby Groot danced to ELO's Mr. Blue Sky while the rest of the Guardians fought for their lives against an intergalactic creature in the background. It was a joy to behold. 

If you thought Baby Groot learned his dance moves from Chris Pratt's Star Lord then you'd be mistaken. They were actually picked up directly from the movie's director James Gunn. 

To mark the occasion of the film having passed the $800m worldwide box office milestone, Gunn shared a video on Instagram of himself dancing and providing the reference for his special effects team to create the dance sequence. 

We are Groot indeed.
