While some characters in Guardians of the Galaxy, like Groot and Rocket, were rendered with computer graphics, the majority of the movie’s aliens were transformed by makeup. Over the course of filming, the movie’s team of 50 makeup artists applied approximately 1,250 prosthetics between the principal cast and alien extras.

Guardians of the Galaxy comes out in theaters on August 1, 2014.
