Wild Geese II is a 1985 British action-thriller film directed by Peter Hunt, based on the 1982 novel The Square Circle by Daniel Carney, in which a group of mercenaries are hired to spring Rudolf Hess from Spandau Prison in Berlin. The film is a sequel to the 1978 film The Wild Geese, which was also produced by Euan Lloyd and adapted from a novel by Carney. Richard Burton, who starred in the first film as Colonel Allen Faulkner, was planning to reprise his role, but died days before filming began. Faulkner is replaced by his brother played by Edward Fox as one of the mercenaries. No characters from the original are featured in the sequel.

Spandau Prison was a former military prison located in the Spandau borough of West Berlin. Built in 1876, it became a proto-concentration camp under Nazi Germany. After the Second World War, it held seven top Nazi leaders convicted in the Nuremberg trials. After the death of its last prisoner, Rudolf Hess, in August 1987, the prison was demolished and replaced by a shopping centre for the British forces stationed in Germany to prevent it from becoming a neo-Nazi shrine.
