Guardians of the Galaxy director James Gunn told the Alamo Drafthouse magazine, BIRTH. MOVIES. DEATH., that the giant floating head seen in the trailers is, in fact, Knowhere, the Guardians’ headquarters, and just like the in the comic books, Knowhere is the skull of a dead Celestial.
We have a couple of Celestials who we refer to in the film. They’re part of the overall structure of the cosmic universe. They’re part of the fun of what the movie is. Our characters, to some degree, have super powers, but at the same time they’re just ordinary citizens of the galaxy. They just happen to be renegades – they’re basically bikers. They’re just these ordinary citizens who get caught up in this thing – because they want money in the beginning – that has completely cosmic overtones. There are characters like Thanos involved, and then there are characters [the Collector, the Celestials] bigger than that. Suddenly these mortals are playing in the fields of gods. I always find that a very interesting thing.
The Celestials are an ancient, galaxy-spanning, immensely powerful race that helped create humanity and figure prominently in the backstory of many cosmic entities in the Marvel universe and could serve as links to other Marvel movies, from Thor to the Avengers to the planned Doctor Strange flick.
