The US animated television series (created by animator Genndy Tartakovsky) aired on both Cartoon Network and Toonami from 2001 to 2004 and featured the eponymous hero as a sword-welding warrior attempting to make his way back to the present, having been transported to the future by an evil demon.
A version for the cinema was mooted back in the early noughties but never came to fruition (perhaps the director attached back then, Brett Ratner, ultimately decided animation adaptations were too effeminate?) but it certainly seems like a good visual match for Singh. With Immortals underperforming somewhat on its opening weekend, he may have to wait and see how Mirror, Mirror fares before he swings into action on this.
