I cannot find any information about this! It’s not listed on IMDB and searching Google is no help at all. The only bit of information I could find was posted in the Youtube description:
A trailer from the new film The American SteamPunk by Greg Ansin and Michael Neel.
I wonder what’s the story behind this film? They have a website domain, with a page that announces the film and links to the trailer. I will email the producer and update this post when I get any news.
