Lame mercenary movie which depends on its name stars . There are thrills , a love story , revenge , chases , emotion and explosions galore . This is a story of vendetta played by familiar faces against the background of the adventures of a bunch of mercenaries led by Major Grigsby . As two soldiers of fortune , Harry Grigsby (Stanley Baker of Zulu) and Kip Thompson (Alex Cord of Mafia) , used to be the best of friends when they battle side by side in Africa . Their mission meets an unexpected turn when Harry is betrayed by their backers . As Thompson double-crosses Grigsby and this one seeks vengeance . While he is London healing from illness , Harry falls in love for gorgeous wife (Honor Blackman of Goldfinger) of a British General (Richard Attenborough of The great escape). Then Harry and his group (Andrew Keir , John Thaw , Julian Glover , Rafer Johnson) are assigned a new mission that they happily accept : to kill Thompson , now in Hong Kong causing disputes with neighboring China by creating frontier tensions . As Harry and his team breaking into Red China someone has to end the madness .
This warlike film packs adventures, large-scale blow-up , routine plot , and lots of action for the most part , but packs also too much dialogue . It's an average mix of action-packed , adventure , romance , thriller and wartime genre . Middling screenplay by Kenneth Ware based on the novel titled "The Ordeal of Major Grigsby" by John Sherlock . Other chief excitements about the movie, will be in the intervention of famous British secondaries who realize professionally competent interpretations , some of them with no more than a line or two to say such as Andrew Keir of ¨Quatermass and pit¨ , John Thaw of ¨The Sweeney¨ and ¨Julian Glover of ¨Game of thrones¨ . Cinematography by Alan Hume is quite nicely , capturing the atmosphere of everywhere , as it was filmed on location in Hong Kong, China , Shepperton Studios, Shepperton, Surrey, England and Spain ; however being necessary a right remastering. Atmospheric as well as evocative musical score by John Dankworth . The motion picture was regularly directed by Gordon Flemyng , father of actor, Jason Flemyng .Gordon directed several episodes of famous series such as ¨The Saint¨ , ¨The Bill¨, ¨Taggart¨ , ¨Avengers¨ and occasionally for cinema such as ¨Doctor Who and the Daleks¨ , ¨Daleks' Invasion Earth: 2150 A.D.¨ , ¨Just for fun¨, ¨Catherine the great¨ and ¨The Split¨ .
