Children of Men (2006)
Budget: $76 million
Gross: $36.5 million
Despite how well-known the film is for its legendary “long-take” scenes, selling audiences on an Uber-bleak sci-fi dystopian film with an R-rating is always a tough task (for more information on that, refer to the previous entry). It’s found a massive audience since it’s theatrical run and still stands as one of the best modern sci-fi movies out there.
