'Carpenter, John' directed this movie about Elvis Presley who, in Change of Habit (1969), played a character called John Carpenter.
Kurt Russell made his film debut in It Happened at the World's Fair (1963) which starred Elvis Presley. According to Russell, Presley was 27 years old when he did "...World's Fair" and Russell was 27 years old when he did this film.
John Carpenter was hired to direct this movie after having written the score for Halloween (1978). The execs figured that, since he knew something about music, he must know about Elvis Presley.
Elvis Presley's father Vernon was played by Kurt Russell's father, Bing.
One of three films that Elvis Presley and Kurt Russell have in common. Russell appeared in the Elvis movie "It Happened At The World's Fair" (1963), he portrayed Presley in the TV movie "Elvis" (1979), and he played an Elvis impersonator in "3000 Miles to Graceland" (2001). In "It Happened at the World's Fair," Russell (who was a young boy at the time), ran on screen and kicked Elvis in the shin. In "3000 Miles to Graceland," this scene is parodied when a young boy runs on screen and kicks Russell (in full Elvis attire) in the shin.
Shown on TV in America, it was released in theaters overseas, a common practice for TV movies at the time.
Only instance in which real-life father and son - Bing Russell and Kurt Russell - play that very relationship.
According to John Carpenter during his DVD Commentary on _Big Trouble In Little China (1986)_ with Kurt Russell, the reason he got the job directing this film was because the producers found out he did the music for Halloween (1978) and figured he could handle a biopic of Elvis.
