New information is emerging over the origins of an anti-Islamic video which is at the centre of violent anti-American protests in Egypt and Libya.
A film was shot in the US, and was shown at a small cinema in Hollywood at the end of June. But it is the clips posted to YouTube, translated into Arabic, which appear to have sparked these protests.
The video first appeared online on 1 July, posted in English by someone using the pseudonym "sambacile."
It was very badly made and cheaply produced, with poor acting and little in the way of storyline.
The most offensive comments about Islam and the Prophet Muhammad had been quite obviously dubbed onto the soundtrack afterwards and not spoken by the actors.
One actress featured in the film said she had no idea it would be used for anti-Islamic propaganda and condemned it.
Cindy Lee Garcia, from Bakersfield in California, was quoted by the website Gawker saying she had a small role in the film which she was told would be called Desert Warriors, about life in Egypt 2,000 years ago.
She threatened to sue the director for the way the actors were represented.
Questions asked
In fact a film called The Innocence of Bin Laden was shown at a small independent cinema on Hollywood Boulevard called the Vine Theatre on 30 June this year.
Someone present, who asked not to be identified, said it lasted about an hour, had very poor production values and attracted just a handful of viewers in the two showings that evening.
He said the man organising the screening was an Egyptian living in America who had hired two Egyptian security guards for the evening.
