According to the Lost Media Wiki - Santo Gold's "Blood Circus" (1985 Rarely-Screened Sci-Fi Movie): - Wikia

"Blood Circus hasn't been shown publicly since 1987, and was thought to be lost for years, until it was announced on the Santo Gold website in 2008 that they had re-discovered a 35mm copy of the film, and were looking for producers for an official release. Despite this, no producers signed on, and the original 35mm film reels were eventually offered up on eBay in 2011, with a starting price of 21 million dollars and a buy-it-now price of 750 million (including insurance), or an option to buy a partnership in the film. No bids or partnerships were made, and the reels didn't sell. Two and a half years later, in late December of 2013, the reels for the film were once again offered up on eBay, (albeit through a different seller), though the highest bid fell below the reserve price and the reels therefore went unsold; the auction has not yet been relisted"

According to IMDB, 'only three people showed up to the premiere: an extra and two movie critics'.
