Broken Allegiance is a fan film that made its debut on the internet in April 2002, created by Australian fans of the Star Wars franchise.

It tells the story of two Sith apprentices, Ruan and Calis, who have escaped the Empire by fleeing Coruscant in a stolen transport. They must fight for their freedom when Darth Vader sends the vicious bounty hunter Korbain Thor to track them down.

The film started pre-production in January 2001, and was shot both in studio and on locations around Melbourne in Victoria, Australia.

Since its release, the film has been downloaded worldwide in excess of 1 million times. A sequel project was announced in 2003, but was cancelled in 2005 when the director decided to pursue an original feature film concept.
