In the late 1950s Mike Todd went to Moscow to discuss possible co-production deal. The proposed productions were to be shot in TODD-AO process, so a TODD-AO camera and DP-70 TODD-AO projector were shipped to Mosfilm studios to demonstrate system abilities. Midway into negotiations Mike Todd returned to the US and then died in an airplane crash. The project was abandoned. However the TODD-AO equipment remained in Moscow, and has been disassembled and studied at the NIKFI (Research Institute for Cinema and Photographic Technologies). The research on TODD-AO system was incorporated into Soviet 70mm film process, called Sovscope 70, and the original camera was reassembled and modified to run 70mm negative. It was used in production of "Poem of the Sea" together with 70mm hand-held camera and TODD-AO inspired 70mm studio camera manufactured by NIKFI, leading to the impression that the film was shot in TODD-AO. Since no 65mm negatives were used in this production, it would be correct to state that the filming process was Sovcope 70, even though one of the cameras was originally created for TODD-AO.
