The composited camera negative of "Citizen Kane" is believed to be lost forever. The most commonly-reported explanation is that it was destroyed in a New Jersey film laboratory fire in the 1970s. However, in 2021, Nicolas Falacci revealed that he had been told "the real story" by a colleague, when he was one of two employees in the film restoration lab which assembled the 1991 "restoration" from the best available elements. Falacci noted that throughout the process he had daily visits in 1990-1 from an unnamed "older RKO executive showing up every day - nervous and sweating". According to Falacci's colleague, this elderly man was keen to cover up a clerical error he had made decades earlier when in charge of the studio's inventory, which had resulted in the original camera negatives being sent to a silver reclamation plant, destroying the nitrate film to extract its valuable silver content. Falacci's account is impossible to verify, but it would have been fully in keeping with industry standard practice for many decades, which was to destroy prints and negatives of countless older films deemed non-commercially viable, to extract the silver.
