Plot

Men posing as reporters board a British supply ship, the Esther, as it carries supplies to a North Sea oil rig and production platform. Once there they pull guns and take over the vessel.⁶ Under cover of the normal transfer of supplies, two members of the gang submerge and attach electronically controlled limpet mines to the base of the rigs, and the ship itself is boobytrapped.⁴

The gang's leader, Lou Kramer (Anthony Perkins), then announces his demands: £25 million within 24 hours, divided among five different currencies, which he presents as a joke about the instability of the money market.⁴ With few other options, the British government accepts the help of ffolkes, a wealthy, misogynistic eccentric who leads a crack commando unit; weeks earlier he had accepted a commission, arranged through an insurance company, to devise contingency plans against exactly this kind of piracy.⁶^•⁴ In the climax, Kramer nearly reaches the trigger for the bomb, but ffolkes disables it in time, and Kramer and the other terrorists are killed.⁶

Cast and characters

Roger Moore, at the height of his James Bond fame, plays ffolkes, a bearded, cat-loving, needlepoint-working underwater demolitions expert who dislikes women and drinks straight shots of vintage whiskey; the character's surname is spelled with a lower-case f.⁷^•⁴ James Mason plays the phlegmatic Admiral Sir Francis Brindsen, and Michael Parks plays Kramer's principal henchman, a myopic electronics wizard.³^•⁴ Faith Brook plays the Prime Minister, who consents to let ffolkes try his approach rather than yield to blackmail, and Lea Brodie plays the Esther's cook, whose failed attempt to poison Kramer nonetheless positions her to save the climactic night infiltration from disaster.⁸^•⁴ The supporting cast includes David Hedison, Jack Watson, George Baker, Jeremy Clyde, and David Wood.⁸

Production

The film was a Cinema Seven production for Universal Pictures, distributed by Cinema International Corporation.⁸ Filming took place between April and May 1979 at Galway Docks in Galway City and in Kinvara, County Galway, Ireland, with studio work at Pinewood Studios in Iver Heath, Buckinghamshire.⁵ The British Film Institute lists the running time as 100 minutes, while IMDb lists 95 minutes.¹^•⁹ The composer was Michael J. Lewis, the cinematographer Tony Imi, and the production designer Maurice Carter.¹⁰

The original UK cinema version removed a shot of one of the hijackers unbuttoning the blouse of a female captive to obtain an 'A' certificate; later video and DVD releases were uncut and rated '15'.⁹

Release and titles

The film's naming history is unusually tangled. It was released in the UK as North Sea Hijack and in the United States as ffolkes, with the US wide release on April 18, 1980 through Universal.²^•³ When it reached American television in 1983 it was renamed Assault Force.² A 2020 Blu-ray from 88 Films carried the North Sea Hijack title.⁸

Reception

The film earned a Metascore of 58 from seven reviews.¹¹ Gary Arnold of The Washington Post called it "an admirably crisp, incisive counter-terrorist thriller, the most proficient and entertaining movie of its kind since Richard Lester's Juggernaut".⁴ The Associated Press's Bob Thomas wrote that director Andrew McLaglen "knows his way around an adventure movie" and keeps the action moving with characters who are larger than life but fairly plausible.¹¹ Time Out was more critical, finding Moore's character smug and calling the misogyny excruciating.¹¹ On Rotten Tomatoes the film holds a 43% Tomatometer from seven reviews.¹²

Commercially it underperformed: the domestic gross was $2,993,772, with the opening weekend accounting for 26.9% of the total, and the film averaged a one-week run per theater across its 398 theaters.³ The railway movie database records that the film "was not a success though it is enjoyable".²

Legacy

Retrospective commentary has treated the film as an early example of the siege-and-rescue formula later popularized by Die Hard: the film-authority review calls it "a precursor of Die Hard" and notes that Roderick Thorp was writing the novel Nothing Lasts Forever, later filmed as Die Hard, while North Sea Hijack was being shot in 1979.⁷ The same review describes the film as an Alistair MacLean-type thriller built on a siege or hostage situation, in which the terrorists are effectively robbers seeking to swindle the authorities out of money, and credits it with a cult following despite what it calls glaring plotting flaws.⁷ A Film Stories retrospective ranks the performance among the more intriguing of Moore's non-Bond roles of the period, made between The Wild Geese (1978) and The Sea Wolves (1980) with the same director.¹³
