Paul eventually went straight and joined Her Majesty's Navy

Although Paul Harrison (Sean Bury) was a troubled child, and his affair with Michelle (in this film and the '74 sequel) brought about much contention with his father, he eventually did turn his life around.

In 1976, he joined Her Majesty's Navy, and went aboard the HMS Ranger. Then his ship was sabatoged by one Curt Stromberg, and the British Secret Service's most celebrated agent, James Bond 007 went on the mission to rescue him. You can see Paul, James, Stromberg, and Russian agent Major Anya Amasova in the great movie THE SPY WHO LOVED ME!!

(Sean Bury aka Paul Harrison can be seen at the very beginning of THE SPY WHO LOVED ME, he is the sailor who is yawning, and watches the other sailors' chess game)
