Doesn't appear to be for sale. Following quote from the site:
"Once finishing funds are secured, a post production process of about 9 weeks should complete the feature version. As editing continues, there is an offline digital "Work in Progress" version of about 90 minutes. The Cinerama Adventure is still privately financed at this time and we are seeking the finishing funds to complete post production items such as scoring, online editing and computer graphics, plus securing some music and stock footage rights."
