Hilton later became CEO of the film production company Essential Media, and the film that immortalizes his illegal climb in 1987, was his first filmed creative endeavour. Glenn Singleman is widely known for his base jumping and wingsuit adventures and for BaseClimb, the epic film in which he base jumps from The Great Trango Towers in Pakistan."
