The Saturn Award for Best Actor is an award presented annually by the Academy of Science Fiction, Fantasy & Horror Films to honor the top works in science fiction, fantasy, and horror in film, television, and home video. The Saturn Awards were devised by Dr. Donald A. Reed, who felt that films within those genres were never given the appreciation they deserved. The physical award is a representation of the planet Saturn, surrounded with a ring of film. The award was initially and is still sometimes loosely referred to as a Golden Scroll. The award for Best Actor was first introduced in 1976 for the 1974 and 1975 years, to reward a lead performance by a male actor in film.
