I remember I had asked an experienced muslim Wikipedian about whether or not my user page violates WP:UPNOT. And he told me that it doesn't! Apparently Wikipedia allows some description of our personal beliefs on our page. And as for the movie, I have no connection or commercial ties with it. The movie was just recently released in Iran and Canada and it has received many positive reviews. And I thought it can help to counter the wave of Islamophobia in the West. And this has actually been one of the motives of the movie's producers. And that's also why I thought it is useful to share it on my page. However if it qualifies for "blatant" promotion I have no protest. But I really don't have any commercial relation with that!
