Despite very good reviews, and staying well within budget, Serenity didn’t do so hot in the box office it turns out. All is not lost. Amazon still ranks Serenity as #3 in DVD sales, with Firefly close behind in #5.
As Joss put it:
DVD sales should, however, put Serenity back in the black and when the bucks start rolling in we can only hope that one of the suits at Universal looks at the numbers, adds the success of the Firefly DVD box set and greenlights a return for Captain Reynolds and his crew.
