There is the small fact that Ahmed Abu Khattalah, the leader of the militia that carried out the attack on the Benghazi consulate has stated that the attack was motivated in part as revenge for the film Innocence of Muslims, which had just been released.  According to the New York Times:   

"Mr. Abu Khattala told other Libyans in private conversations during the night of the attack that he was moved to attack the diplomatic mission to take revenge for an insult to Islam in an American-made online video."
