The movie 'Supergirl' has opened with a lower than expected box office result, with reported earnings of $38 million in its opening weekend in the US, while 'Toy Story 5' remains at the top with $70 million. However, there is some discrepancy in the reported global box office opening for 'Supergirl', with one outlet stating it earned $68 million. The performance of 'Supergirl' is being described as disappointing, with potential losses estimated, although the exact figure varies.
