Sony cancelled the theatrical release of The Interview after constant warnings by North Korean hackers and a majority of theaters pulling out due to safety concerns. Won't even bother with skipping to a DVD/VoD release either.
Besides the threats of "9/11"-like attacks, the hackers were also planning on releasing the bulk of data they still have out in the public had the film been released.

US already confirmed North Korea was behind the hacking attack and are considering tough sanctions as punishment. Last time they were severely punished by the US, the government came really close to collapsing.
