The Third Secret
“The Story of a Man Searching for a Killer Who Might Be Himself!”
Synopsis
A prominent London psychologist seems to have taken his own life, causing stunned disbelief amongst his colleagues and patients. His teenage daughter refuses to believe it was suicide as this would go against all of the principles her father stood for, therefore she is convinced it was murder. She enlists the help of a former patient to try to get to the truth. However, the truth turns out to be both surprising and disturbing.

How many hands made this film
The scale of the collaboration
Principal cast & crew: 16
These are the principals we have on file — the full crew ran to the hundreds. Every film this size was made by far more hands than any credits list ever names.
Why a floor?
This is a minimum, not a total. We only count the credits we’ve captured so far, and coverage is uneven — a blockbuster might show a few hundred names while another of the same size shows a couple dozen. The real crews all ran into the thousands. The number here only grows as full credits are enriched — so we frame it as a floor, never a headcount.
