A new documentary about the 2014 Sony hacks will reportedly "examine alternative theories" about the culprits behind the attacks on the film company.
The film is being made by Jehane Noujaim and Karim Amer, the duo behind the 2013 Netflix documentary The Square, which told the story of the 2011 Egyptian Revolution, and was nominated for three Emmy Awards.
The Sony hacks, which took place in December 2014, saw confidential companyl data, including private emails, film scripts and employees' personal and financial details, stolen and deposited online.
Sony Motion Pictures Chairperson Amy Pascal eventually resigned, after emails came to light in which she and producer Scott Rudin made a number of jokes relating to President Obama's race.
The hackers, who identified themselves only as the "Guardians of Peace", were believed to be working on behalf of North Korea, and acting in response to the Sony film The Interview, which featured the assassination of the North Korean leader Kim Jong Un.
On December 19, President Obama formerly identfied North Korea as the force behind the cyber attack. To date, however, the country has denied any part in the hack.
According to Hollywood Reporter, a number of experts and people in the cybersecurity community "believe that the attack likely was an inside job, given that the hackers exhibited intimate knowledge of the architecture of Sony’s servers".
