Hackers have promised that "the world will be full of fear" following the Christmas day release of "The Interview."
"Remember the 11th of September 2001," the hackers write in a new note reportedly posted Tuesday on Pastebin, a site that lets people easily share text.
Officials from the Federal Bureau of Investigation and the Department of Homeland Security told The Huffington Post that they were aware of the threats and investigating them. However, the official from the Homeland department, who declined to be named, emphasized that "there is no credible intelligence to indicate an active plot against movie theaters within the United States."
"The FBI continues to work collaboratively with our partners to investigate the Sony attack," Jennifer Shearer, a representative for the FBI, told HuffPost.
The chief executive of Sony Entertainment, Michael Lynton, confirmed that the company is working with federal agencies, sending this email to employees Tuesday:
"We are aware of the latest threat and are working closely with the FBI and other law enforcement agencies. Please remain vigilant," Lynton wrote in the email, which was forwarded to HuffPost by a Sony employee. He added that workers should contact the FBI if they have "information relevant to the investigation."
Stars James Franco and Seth Rogen cancelled press appearances intended to promote the film at least through Thursday, and a reporter from the L.A. Times tweeted that theater owners are considering pulling the movie over the threats.
The hackers warn people to stay away from places screening "The Interview," a comedy about the assassination of North Korean leader Kim Jong-un distributed by Columbia Pictures, a division of Sony Pictures Entertainment, according to reports in Buzzfeed and Fusion.
"How bitter fate those who seek fun in terror should be doomed to," the note reads.
Sony has recently been subjected to a massive leak of internal documents following a hack by a group calling itself Guardians of Peace. The company has demanded that news outlets refrain from reporting on the information released through the hack.
The new message is the first to directly threaten violent action. According to Variety, it reads in full:
Warning
We will clearly show it to you at the very time and places “The Interview” be shown, including the premiere, how bitter fate those who seek fun in terror should be doomed to.
Soon all the world will see what an awful movie Sony Pictures Entertainment has made.
The world will be full of fear.
Remember the 11th of September 2001.
We recommend you to keep yourself distant from the places at that time.
(If your house is nearby, you’d better leave.)
Whatever comes in the coming days is called by the greed of Sony Pictures Entertainment.
All the world will denounce the SONY.
