The first impression I got from the preview of Firefly was that it was much like WALL-E. The main character of the former is very reminiscent of the latter's, and the few details that have come out about the short hint at an outer space vibe. It's rendered with Pixar's Renderman technology, which explains some of the familiarity. Not much has been revealed, but what little has been is intriguing.
What we do know involves the Kickstarter rewards, which are very cool. The main character of Firefly is a coffee-making robot. To that end, one of the rewards is an old-timey coffee tin with the blend from the story. You can get the DVD and/or Blu-Ray, along with a cool laser light. The highest reward includes 3D-printed models of the characters, and an executive producer credit along with a screening of the film.
Firefly is shaping up to be a great project. While there's still a lot to be seen about where the film will end up, but if it's anywhere near as good as its inspiration, it will be one heck of a finished product.
