For Hyperallergic, Munir Atalla compiled a great list of Palestinian films for beginners:
[…] Interestingly, it has often been Palestine’s proximity to journalists, with their power and modern equipment, that has inspired us to take our narrative into our own hands. The result is that a fragmented mess of people — spanning those living under occupation in the West Bank, under siege in Gaza, as second-class citizens in Israel, and a worldwide diaspora — has created one of the richest and most productive collective oeuvres of the Global South.
And if you want more, there are a few Letterboxd lists to try including this Palestinian cinema archive.
