In July, Netflix boasted that the Charlize Theron action film The Old Guard had been streamed by 72m households in four weeks.
Currently sitting atop the list are the 2016 Bruce Willis action film Marauders and the 2018 Jennifer Garner vigilante thriller Peppermint.
Released worldwide on Friday (4 December), Mank has made just one appearance on Netflix’s top 10 list in the US, ranking at number 10 on Saturday, the first day it could chart.
While the top 10 list can’t be used as definitive proof that Mank isn’t being watched by strong numbers, Netflix does tend to publicise when its content proves incredibly successful.
