Of Fathers and Sons (Arabic: عن الآباء والأبناء ʿan al-ʾābāʾ wal-ʾabnāʾ) is a 2017 Arabic-language German-Syrian documentary film directed by Talal Derki about radical jihadism and terrorist training in Syria.

[1] Under the guise of a photojournalist sympathetic towards Salafi jihadism, Talal Derki is allowed to enter a village controlled by the al-Nusra Front close to the front line of the Syrian Civil War, and stays with the Osama family.

The family patriarch Abu Osama is an enthusiastic fanatic, openly praising the September 11 attacks and naming his children after the leaders of al-Qaeda and the Taliban.

After returning home, Abu Osama's treasured books are destroyed in an airstrike by the Russian Air Force, and he lives by selling components from disarmed mines to bombmakers.

At the camp, Osama advances along and is prepared for further military training, while his younger brother Ayman does not do well and wants to return to school.
