"Guardians of the Galaxy" concept artist Jackson Sze has unearthed some of his original concept art for the film, offering up a key frame he designed that was inevitably used -- to great success -- in the final version of the Marvel Comics-based film.

The shot Sze showcases depicts the iconic moment in the film when Rocket and Groot attack, full-blast, the guards at the Xandarian prison compound near the beginning of the film. Unlike most other concept art, this scene was actually brought to life.
