There are many interesting movies and documentaries relating to an aspect of Palestine, which I highly recommend watching:
The Wanted 18. Part animation, part documentary, it is a really funny and touching movie that was nominated to receive an Oscar and received high acclaims by Michael Moore.
Speed Sisters, about an all-female palestinian car-racing team. I must admit that I have not seen this movie, but many people have mentioned to me that it is fantastic and a must see.
Omar. Another Oscar nominated movie with a 91% rating on Rotten Tomatoes, about a Palestinian with a girlfriend on the other side of the wall.
Open Bethlehem, an engaging and inspiring documentary which aims to put Bethlehem on the map as a Palestinian city.
