Grendel Grendel Grendel is a 1981 Australian animated film written, directed and designed by Alexander Stitt and starring Peter Ustinov. It was based on John Gardner's novel Grendel. The music was composed and conducted by Bruce Smeaton and has been released on the 1M1 Records label.

Like Gardner's novel, the film is a retelling of part of the epic poem Beowulf from the monster Grendel's point of view. Grendel (voiced by Ustinov) is by turns a thoughtful and contemplative character and a rampaging monster who attacks the mead hall of an early Danish kingdom, biting the head off of one would-be defender. This was the second full-length fully animated film ever made in Australia (coming after 1972's Marco Polo Junior Versus the Red Dragon).
