It's Guardians of the Galaxy's most beloved scene. But have you ever wondered why Baby Groot froze in place whenever Drax the Destroyer turned to look at him? Director James Gunn actually has an answer.
It actually has to do with an earlier scene that was cut from the movie. Here's Gunn's explanation from Doug Benson's Doug Loves Movies podcast:
There was actually a scene that we cut from the movie where big Groot was dancing to 'Livin' Thing' by ELO. And it wasn't such an elaborate dance. It was more that he was just moving up and down like this, and Drax was dismissive and gave him this look like he was a loser when he did that.
Dancing is ludicrous to Drax. I don't think he understands it. If Drax owned a town, if he was a mayor, the first law would be no dancing. But yeah, so at the end of the movie, little baby Groot didn't want to get caught dancing, because he would kill him.
I just assumed Baby Groot was messing with Drax because it's hilarious, but this works too.
