I’ve also seen some speculation - from websites that seem somewhat informed - that it’s possible that this guy was actually being used by Iran and Egypt as a sort of agent provocateur, without his knowledge. Or even that he is somebody actually in their employ.
He sounds like a somewhat flaky character, so he’d probably be pretty easy to manipulate or to buy.
The “actors” in this thing were told that they were making a movie to discourage Muslim-on-Muslim violence. They seem to have thought it was pro-Islamic.
And the place that strategically published it was...ta da...Egypt.
