The Interview pulled in $15m (£9.6m) from online rentals and downloads in just four days, making it the studio's most successful online film to-date.
The movie, which swept to notoriety following the hack into Sony Pictures, attracted two million rentals and purchases over the festive period as fans clamoured to see what all the fuss was about.
Sony Pictures had initially cancelled The Interview's Christmas Day release after receiving anonymous threats to cinema-goers in the US. The company later reversed its decision after a barrage of criticism, with even President Obama weighing in.
The comedy centres around a fictional plot to assassinate North Korean leader Kim Jun-Un, but this made it a target for cyber attacks from North Korean sympathisers.
At the end of November, a group calling themselves Guardians of Peace hacked into the production company's systems, stealing thousands of pieces of data, including executives' emails and unreleased films. It led to embarrassing revelations such as what staff really think about Hollywood stars Adam Sandler and Angelina Jolie.
While North Korea denied any involvement it did label the act a "righteous deed".
Seth Rogen, writer and director, said:
I'm so grateful that the movie found its way into theatres, and I'm thrilled that people actually went out and saw it.
Rory Bruer, Sony's president of worldwide distribution, said:
We are very pleased with how it is doing both theatrically where we are seeing numerous sell-outs across the country, and online where it remains at the top of many charts.
