Gaza Fights for Freedom (Abby Martin) https://www.youtube.com/watch?v=HnZSaKYmP2s

There are a few others I have saved somewhere, I will search for them and post here when I can.

www.solidaritycinema.com has what you need

I haven't seen many but 5 Broken Cameras is one I'll keep pushing.

Al Jazeera has a wealth of documentaries on this subject. You probably want to start with this one on the Nakba, but literally anything by Ali J is gonna be good.
