Films Paragon's Paragon (1974) Star Trek fan films have been made since the 1960s by individuals and various fan groups but, before the advent of inexpensive digital cameras, editing and effects in the 1990s, most were on a simple home movie level. An early effort to achieve something more was John Cosentino's Paragon's Paragon, which was an unofficial adaptation of James Blish's Spock Must Die!, an early Star Trek spinoff novel. The film ran for an hour and was shot on 16mm film using a full-size recreation of the Bridge set. It also used a wide variety of film special effects techniques on a budget of over $2,000 ($ in dollars) and received considerable coverage in Don Dohler's Cinemagic magazine for low budget filmmakers. Dohler subsequently used its crew to make his first feature film, The Alien Factor (1978).
