Sony Pictures accidentally uploaded an entire film to YouTube, instead of the trailer on Tuesday.
A clip labelled "Khali the Killer: Official Red Band Trailer" made its way onto the video sharing site, but when unsuspecting fans clicked on it, they were able to watch the entire movie.
The 89 minute upload of the crime drama, filmed back in 2016, featured the full credits and clocked up an impressive 11,000 views, the Daily Mail reports.
The trailer has not reappeared online and the only clue to its once existence is a bizarre, broken link.
The grisly flick is slated to open in a few US theatres in August, and has already been released on DVD and Blue-ray in the Netherlands.
