A trailer created by Benjamin Eck that I think looks far better than the current 'in production' one.

In a nutshell, the film will follow Raph after his uncontrollable violence labels him a threat to his family. Master Splinter has no choice but to banish his own son. So, accompanied by Casey Jones he takes refuge in Los Angeles. It’s when his itch for violence sends him out to the streets that he uncovers a high level of organized crime. Getting to the root of it will surely win his place back in his family, but he will quickly discover that he’s not New York City’s only secret hiding on the West Coast.

With enough interest we plan to launch a fund raising campaign to bring this project to life. We hope you'll be as excited as we are to dive into the troubles that follow being a trained ninja assassin.

Raph and Casey Jones together in the sewerless city of LA.

I'd back this.
