Wanting to become an actor, del Campo went to California in 1935, where he soon met Mary Astor. In a ceremony kept secret from the press and his family, del Campo married Astor in 1936, becoming her third husband. Together they had a son, Anthony Paul "Tono" del Campo. In 1941, del Campo joined the newly formed
No. 415 Squadron RCAF as a
Flight lieutenant. The squadron was stationed at
Thorney Island and was armed with
Hampdens. As a result of del Campo's enlistment the couple drifted apart, and divorced amicably in 1941. The marriage, although hardly a success, was a happy one. Astor would later recall Manuel, or "Mike" as she called him, as a kind and decent man, albeit an irresponsible one as well, as he rarely contacted her or their son after the war. After the Second World War ended, del Campo stayed in the UK, where he married two more times. He worked as an editor until his death in 1969 in London. ==Partial filmography==
