Trivia

 * Each Season 1 trailer revealed more of the RWBY logo, with each respective character being added each time.
 * With each trailer, the moon in the background is in a different lunar phase, from a full circle to a waning gibbous and crescent. Interestingly, the moon is not merely shadowed by the Earth like it normally would be, but looks almost to be breaking apart or scattering in rose-like patterns.
 * Creator Monty Oum has stated that this may simply be the lunar cycle for the world of RWBY.
 * In the "Black" and "Yellow" trailers a crow flies by during a scene. This is a signature employed by Monty, akin to the appearance of doves in the works of John Woo.
 * It was stated by Monty in a journal that there would be no trailers for Volume 2, instead, he showed a teaser image for Velvet's Team.
