Last week, the History Buffs YouTube channel (devoted to analyzing historical accuracy of movies) uploaded a detailed and worthwhile review of Lawrence of Arabia. I've explored this topic myself in some detail, but lacking the skill or personal charisma for video reviews, this is a valuable find. We will agree to disagree on the Deraa Incident and other specifics.
This channel has an extensive back catalog, commenting on movies and television past and present, but this is a good place to start. If you have a half-hour to spare, check it out!
