The Spy Who Loved Me 1977

It's the BIGGEST. It's the BEST. It's BOND. And B-E-Y-O-N-D.

Directed by Lewis Gilbert

Russian and British submarines with nuclear missiles on board both vanish from sight without a trace. England and Russia both blame each other as James Bond tries to solve the riddle of the disappearing ships. But the KGB also has an agent on the case.
