I have lots of history on CIA use of film as decoys including 1953 letters from the CIA mole at Paramount Studios back to his handler at the Psychological Strategy Board.

'Dear Owen': The CIA, Luigi Luraschi and Hollywood, 1953
I have been documenting for two years now the CIA control of movies and TV used as counterpropaganda to hide scandals by using decoys with KEYWORD HIJACKING. My threads have the details. Here's how Don Knotts was REALLY used by the USG-
1962-Operation Vulcan Goes Wrong when a limpet mine blows up and 1964 decoy film with Don Knotts becomes its counterpropaganda for American kids,
'The Incredible Mr. Limpet.'

This example is typical of many using the same device, keyword hijacking, to hide topics like-
CIA covert operations
nuclear weapons accidents
election fraud
assassinations
US-Nazi complicity

OPERATION VULCAN
The Secret Side of Tonkin Gulf Incident
.....
In the oily water, Nguyen Huu Thao was in the process of fixing his limpet mine to a Swatow's hull. Hearing a commotion on the deck above, he apparently panicked - and the mine exploded in Thao's hands.
.....
On 21 July. Hanoi placed the captured commandos and crew before a jury. Receiving sentences of up to life in prison, the somber commandos headed for their cells. Photos of their captured equipment were splashed across English-language publications coming out of Hanoi, and one of the commandos was even coerced into making a public condemnation of the program.
In 1962 the CIA was working with teams of divers sabotaging Vietnamese ships with limpet mines. One operation became a PR disaster when a limpet mine went off early and exposed the operation which was trumpeted in English-speaking newspapers in the region. The US was carrying out terrorist attacks on North Vietnam.
The operations continued and were taken over by the Pentagon in 1964.
Eventually the official Gulf of Tonkin hoax led to the fullscale Pentagon assault on Vietnam.
The movie 'The Incredible Mr. Limpet' was promoted in CIA's asset called LIFE Magazine in the 3/20/64 issue with the featured cover photo and article of Ambassador Lodge in Saigon. Very appropriate marketing issue for the limpet mine disaster cover-up film.
Operation Vulcan wasn't the only disastrous scuba covert op.
Scuba terrorism operations had gone very wrong in Cuba, too, according to the 1973 book, 'The Secret Team' by Lt. Col. L. Fletcher Prouty.
Pages 29-34 of 'The Secret Team: The CIA and its Allies in Control of the United States and the World' describe poorly run and disastrous scuba team sabotage raids against Castro's Cuba with the divers killed, captured, and tortured into giving out information.
