Last night was the premiere of Avengers: Endgame. It was an event over 10 years in the making and nearly everybody who has ever been a part of the Marvel Cinematic Universe was in attendance to see how the story came to an end. However, one person who was conspicuous by his absence was James Gunn. The Guardians of the Galaxy director did not attend the gala event last night, but according to his brother, Sean Gunn, explained that he was there in spirit.
