How many different ways can someone say "I am Groot?"
Well, now I know, thanks to this insightful and oftentimes hilarious 12 minutes of b-roll footage from [Guardians of the Galaxy](movie:424073). If the ubiquitous praise pouring out of news outlets is to be believed, this could be Marvel's very, very best, and it's great seeing James Gunn work so well with his cast and crew, and seeing the actors have an absolute blast.
It looks like this is one of those rare productions where the film is as much fun behind the camera as it is in front; well, at least one of the rare cases where saying that is a positive.
So, let's watch green pro-wrestlers violently slam extras into cushions, Bradley Cooper threaten a screen with an invisible gun, and Chris Pratt do his best not to make "Pew! Pew!" sounds while shooting a real one.
