We owe a massive debt of gratitude to Phil Arnold for identifying this gentleman who we have spotted in several Irwin Allen movies, namely The Poseidon Adventure, The Towering Inferno and The Swarm and have long been keen to put a name to his face. It has been through really thorough research that Phil managed to find and verify Jack Krupnick's name by remembering his face from other productions he's researched over the years. We include a picture further down of Jack Krupnick in the long running series Hart to Hart courtesy of Phil Arnold.
