It is my duty to inform you that porn has indeed gone into the final frontier — a reader tells me that The Uranus Experiment #2 (1999) features “the first ejaculation in zero gravity”. Made by European porn company Private, “The scene was filmed by flying an airplane to an altitude of 11,000 feet. The plane, containing performers Sylvia Saint and Nick Lang, then went into a steep dive, creating the momentary illusion of weightlessness.
Insiders described the filming process as particularly messy from a technical and logistical standpoint.
Budgeting constraints allowed Saint and Lang, who portray astronauts, only one shot at a perfect zero-G take, leaving the actors with only a narrow 20-second window of time in which to launch themselves toward one another and complete the scene. ”
And for this they were nominated for a Nebula award. Amazing.
