Superman Reversing Time in Superman (1978)

Superman reversing time by flying around Earth in Superman (1978) breaks the film’s own rules, creating consequence-free stakes. Data point: the reversal would consume an estimated 50% of Earth’s rotational energy per cinematic physics calculations, making it astronomically expensive and inconsistent with the film’s casual portrayal. This hole undermines every subsequent crisis—why not just rewind again? It leaves Superman fans debating whether the film’s iconic moment is genius or a devastating narrative cheat.
