Krull is a 1983 British science fantasy adventure film directed by Peter Yates and distributed by Columbia Pictures. It stars Ken Marshall, Lysette Anthony, Freddie Jones, Francesca Annis, and Alun Armstrong. Liam Neeson and Robbie Coltrane, still early in their film careers, appear in supporting roles. The story follows Prince Colwyn (Marshall) and a fellowship of companions who set out to rescue his bride, Princess Lyssa (Anthony), from a fortress of alien invaders who have arrived on their home planet.

Development on the film began in 1980, when Columbia Pictures President Frank Price gave producer Ron Silverman the idea to produce a fantasy film. Krull was shot in England at Pinewood Studios and on-location in Italy and Spain. Nick Maley designed the creature and prosthetic makeup effects seen in the film. The film score was composed by James Horner and performed by the London Symphony Orchestra.

Krull was released in the United States on July 29, 1983, and in the United Kingdom later that December. The film was a box-office bomb upon release, and critical opinion has been mixed, both upon release and in retrospect. Numerous reviewers have highlighted its visual effects and soundtrack, while several critics have criticized its plot as being derivative and nonsensical. In the years since its release, the film has developed a cult following.
