The Brickfilms Challenge Series, often referred to as BCS, was a recurring brickfilming contest hosted officially on Brickfilms.com. It was started by Saul Goode, the Minister of Film Contests at the time, and its aim was to inspire creativity and experimentation in certain aspects of brickfilming, with plans for a new challenge every two to three months. It ran three times, all within 2008, and with gaps of three and five months. It changed hosts often throughout its run, as it took place over the time when the community were leaving for the site that would become Bricks in Motion and staff of Brickfilms.com were stepping down, amid tensions with the new owners of Brickfilms.com.
