YouTube is coming under pressure from governments worldwide over the film said to insult Islam.
Parent firm Google has already rejected a request from the White House to take down the movie.
Now a court in Russia is mulling whether to classify the ‘Innocence of Muslims’ as extremist material.
A new law effective from November 1st would enable Russian regulators to block the entire YouTube site.
Afghanistan, Pakistan and Bangladesh have already blocked YouTube.
Saudi authorities have threatened to follow suit unless Google removes all links to the film.
The company is restricting Indian and Indonesian access to the clips to comply with local laws.
