Action-packed suspense thriller finds innocuous-looking purser Carter (Harris) the unlikely hero when the floating casino on which he works is hijacked by a heavily armed group of mercenaries, led by John Vernon. Complicating matters, a nuclear warhead has been smuggled aboard as collateral for a rendezvous with another ocean liner, loaded with gold bullion. A cast full of supernovas, dazzling set & stunt work, and a catchy theme tune by Jeff Wayne create a pleasing audio-visual experience light on logic but fast paced and entertaining nonetheless.
