Sony has canceled tours of its Culver City, California studios in the wake of hacker threats which have already scuttled the release of the Seth Rogen and James Franco film, "The Interview."
Tours were canceled last week and will not resume this year, The Hollywood Reporter said.
The two-hour guided walking tour takes guests through sound and scoring stages as well as the sets of television shows such as "Jeopardy" and "Wheel of Fortune," according to the website.
The studio is concerned that someone could stray from the group, TMZ reports.
As of this writing, tours through Jan. 2 are listed as "sold out" on the ticketing website, and no dates are available for purchase beyond that point.
On Wednesday, Sony canceled the release of "The Interview" after hackers who stole corporate documents, emails and other data threatened terror attacks on any theater showing the film.
The movie is a comedy about a plot to kill North Korean dictator Kim Jong Un. The U.S. government reportedly believes North Korea is behind the attack and the threats.
