Down in it (1989). his is not a movie but a Nine Inch Nails videoclip. The clip showed Trent Reznor running on roofs and falling to his death. The FBI thought all was real. The band used a bunch of cameras by throwing them off roofs to simulate a fall and lost one when it flew away; that camera caused a stir. When they made the camera fly up, to reverse the footage later, it went loose and later landed on a field. When a farmer found the camera he went to the Police and they contacted the FBI. The experts from FBI estimated that Reznor was a three week old corpse and the rest of Nine Inch Nails was a notorious gang that killed him. It was in 1989 so the band wasn't famous yet so no one recognized the corpse to be a much alive musician, Reznor showed up to prove he's alive and that pretty much ended the investigation; but still the clip was censored for TV.
