It could be only a matter of time before The Interview is made public.

The film - a comedy depicting the assassination of Kim Jong Un - will no longer be released, after North Korean hackers made terror threats against the theatres showing it.

Wall Street Journal correspondent Erich Schwartzel says in this day and age, it'll be hard to hold back the film.

He says the hackers must have a copy of it, because they've also released several other forthcoming films from the studio.

Erich Schwartzel says the reviews for the film aren't very good, but the publicity has made everyone want to see it.
