Yes, I know about this. Not any more than anyone else though. It's a supposed mockumentary about Spongebob, but no one knows any of the details. Pretty sure any other information beyond that isn't available.
The whole thing was some sort of cover up for some illegal activity involving money or something.
the website for the people who made it downloads a virus that tracks your computer, even googling the company can do this somehow.
The guy investigating it has dropped off the face of the earth.
Although you can not purchase it you can stills see the listing on Amazon and read the comments. Nothing weird about this, just a shitty movie of a guy in a sponge bob costume running around with some kid in Hollywood. The company was faced with lawsuits by Nickelodeon.
