North Sea Hijack (1980), also released under the alternate titles ffolkes and Assault Force, is an action film starring Roger Moore, James Mason, Anthony Perkins, and Michael Parks. It was directed by Andrew V. McLaglen and adapted by Jack Davies from his novel Esther, Ruth and Jennifer. This film was a vehicle for both Moore and Perkins to try to escape typecasting. Previously Moore had been practically typecast as a womanising, happy-go-lucky playboy in such series as The Saint, The Persuaders! and James Bond. In contrast to those parts, he is shown here as a bearded, eccentric, arrogant cat-loving misogynist. Yet he does show heroic qualities and is a master strategist. Moore once said in an interview that he preferred this film to all the James Bond movies he had starred in.
