Up Periscope (1959)

In the heart of 1942 California, Lieutenant Kenneth M. Braden, a courageous diver from the U.S. Navy demolition team, is caught in the throes of a blossoming romance with the enigmatic Sally Johnson. As their bond deepens, he daringly proposes, only to be met with her reluctant request for more time. An unexpected summons disrupts their love story, sending Braden across the vast blue expanse to a clandestine base in the Pacific. In a twist of fate, Braden discovers Sally's true role as a Navy operative, tasked to scrutinize his aptitude for a mission shrouded in secrecy. Putting his personal feelings aside, he embarks on a perilous assignment that will test his mettle and loyalty. On board the hulking submarine Barracuda, under the stern command of Commander Paul Stevenson, Braden is covertly transported into the hostile territories of a Japanese-held island. His mission is as dangerous as it is vital: to stealthily photograph secret radio codes that could turn the tide of the war. "Up Periscope" is a thrilling exploration of love, duty, and courage, where personal emotions clash with the call of patriotism, and survival hinges on a single click of a camera.

Up Periscope is an action movie featuring James Garner.
