I CANNOT, YET I MUST is the amazing story of ROBOT MONSTER, the legendary 1953 gorilla-wearing-a-diving-helmet no-budget epic that sums up an entire era of film history. Determined to crack Hollywood and fully aware of what he was up against, director Phil Tucker crafted a profitable 3-D feature with very little money and very much ingenuity. Fascinating, surreal, hilarious and an incredible testament to getting the job done even when it is impossible, ROBOT MONSTER is now documented in detail. From the ballyhoo of producer Al Zimbalist to the eccentric life of writer Wyott Ordung, from Phil Tucker's previously unpublished memories to the significantly different script, I CANNOT, YET I MUST is the book that finally explores ROBOT MONSTER!
