In an effort to literally be the most charming franchise in the history of film, Guardians of the Galaxy has been releasing blooper reels online and they're all amazing. It looks like such a fun, emotionally-healthy and professional set filled with people who are all friends. It really comes out in the final product when everyone gets along. It really makes you wish you were there.
Watch the video if you want to crack a smile.
Bonus: Rocket Raccoon and Groot are in the blooper real, which means that they planned this ahead of time. Awesome.
