In 1972 the QE2 was subjected to a bomb hoax and Royal Marines were deployed to deal with the situation: this is an adaptation of that incident, with writer/producer Richard Alan Simmons (writing under the nom de plume Richard De Koker) moving events to the North Atlantic and a cruise liner tellingly christened Britannic. An Irish-accented man telephones the owner of the line Ian Holm with the information that seven drums of amatol (an explosive) are rigged in the hold. He wants a half million ransom.The seas are too stormy to save the 1200 passengers and while the police led by Anthony Hopkins (whose wife and son are on board) race against time to track the phonecalls, Navy bomb disposal expert Richard Harris and his team including David Hemmings are winched to the ship to try and defuse everything. This came out at the height of the Arab oil crisis and the IRA’s mainland Britain bombing campaign – and – crucially – the disaster movie genre. Yet it has a rare degree of realism and character definition, probably because after the original directors Bryan Forbes and then Don Medford abandoned ship (!) Richard Lester took over and rewrote it with Alan Plater, demonstrating that he is as adept at action/adventure as slapstick comedy, with regular Roy Kinnear along for the ride, supplying some morbidly funny lines as the entertainer while the clock ticks. While Captain Omar Sharif sweats and looks a little red around the eyes, even with Shirley Knight providing his kicks, Harris smokes his pipe and gets on with the job. He does some really great character work given that most of his acting takes place in quite literally a tiny frame – head and shoulders. The revelation of the bomber’s identity – he’s not foreign – provides some thought-provoking context. Free of contemporary technology and with some telling lines about refugees, this is an unusually watchable genre exercise, driven by something deeper than just explosions and with a really great ending.
