According to the Guinness Book of Records, at the time of its release, this was the most expensive film ever made at a total production cost of $46 million. However, following the release of Superman II (1980), total production costs of $109 million were attributed to the first two Superman films, which were shot simultaneously as a single production. The producers of the Superman films then retroactively attributed a cost of $55 million for Superman (1978), and $54 million for Superman II (1980), therefore claiming that Superman (1978) was the most expensive film made at that time.
