Trivia

In an effort to get the studio executives to commit to making the movie, Zack Snyder and his team scanned every image from Frank Miller 's graphic novel into a computer. They then removed all of the dialogue and descriptive prose, and added simple animation to each frame (such as burning fire, moving clouds, sparkling eyes etc.). They then edited these shots together into what amounted to an animated comic strip, and Snyder hired his friend Scott Glenn to record a voice-over narration for the piece. Snyder brought the film to Warner Bros., but they said they needed more to convince them that the movie could work. As such, he decided to shoot a live-action 'test' - a 90-second 360-degree continuous shot featuring a single Spartan killing several Persians. The combination of the animated comic images and the test convinced Warner Bros. that Snyder and his team were capable of making the movie. An extract from the animation as well as the entire test can be found as an Easter egg on disc 1 of the 2-Disc special edition DVD of the film. See more
