Captain Kronos – Vampire Hunter is a 1973 British swashbuckling action horror film, written and directed by Brian Clemens, produced by Clemens and Albert Fennell for Hammer Film Productions, and starring Horst Janson, John Carson, Shane Briant, and Caroline Munro. The music score was composed by Laurie Johnson, supervised by Philip Martell. Shot in 1972, but belatedly released in 1973 in the UK, the film was intended as the first in a series focused on the title character and his companions. Due to the film's violence and sexual subtext, Captain Kronos was rated R in North America. This was Clemens' only film as a director.
