A group of activists calling themselves Guardians of Peace have warned movie executives at Sony to scrap plans to release Seth Rogen's new comedy The Interview or risk another major systems hack.

The organisation is claiming responsibility for the hack attack, which led to the leak of unreleased Sony films and information about top stars, and officials insist there may be more leaks to come.

A message from the group reads: "Stop immediately showing the movie of terrorism which can break the regional peace and cause the War! (sic)."

The Interview follows the fortunes of two American journalists hired by the Cia to assassinate North Korean leader Kim Jong Un.

The film is set to open on Christmas Day (25Dec14) and the premiere is set for Los Angeles on Thursday (11Dec14).
