Royal-watchers, of course, will be especially attuned to details about what it was like growing up with glamorous Princess Diana as a mother, and Harry's front-row seat to his father's affair with his now-wife, Camilla Parker-Bowles.

The film tells the story of Shaar's efforts to set up a food truck and harness the culinary talents of the women living in the refugee camp of Burj al Barajneh, which was established in a southern suburb of Beirut in 1948 and is still home to thousands of Palestinians.
Shaar's project "Soufra" - which means a table laden with food - drew the attention of Hollywood actress and social activist Susan Sarandon, whose documentary - also called "Soufra" - was screened for the first time this week in Beirut.
