North Sea Hijack (released as ffolkes outside the UK and as Assault Force on US TV[1]) is a 1980 British adventure film starring Roger Moore, James Mason, Anthony Perkins and Michael Parks.

In contrast to those parts, he portrays a bearded, eccentric, arrogant, cat-loving chauvinist with master strategist skills who does needlepoint embroidery and drinks scotch whisky immoderately.

Eccentric and cat-lover counter-terrorism consultant Rufus Excalibur ffolkes is asked by Lloyd's of London to develop a contingency plan, should any of the North Sea oil installations it insures be threatened.

Months later, a North Sea supply ship named Esther takes on board a group of men posing as reporters who are to visit the oil production platform Jennifer.

The leader of this group, Lou Kramer, hijacks the ship; the gangsters attach limpet mines to the legs of Jennifer and its accompanying oil drilling rig, Ruth, then issue a ransom demand for £25 million to the British government.

With his original plan thus upset, ffolkes persuades the Prime Minister to have the ransom helicopter drop off a bomb on Esther in case his team fails to take out Kramer's gang in time.
