This movie, grand in scope, feels like a classic. Based on a true story, it's about a flamboyant, complex, unique, and sometimes enigmatic British officer who leads the Arab tribes, despite internecine fighting, against the Turks during World War I, and, notwithstanding British misgivings, encourages their independence. As such, it plays simultaneously like a character study / psychological profile and an adventure story. The film, at nearly four hours in length (with an intermission), feels stately in style and in pacing. One can't make movies this long or at this speed anymore. Thus, it's unrepeatable. A solid film, it's not a surprise that it won many Academy Awards and Golden Globes.
Speaking of the intermission, I liked the musical score that played during it, before the movie started, and at the end.
The film includes dramatic, expansive desert vistas. The battle scenes had a similarly wide angle and used many extras. According to the commentary, shooting in a pristine desert was hard work. One had to rub out tracks (or wait for the wind to do it for you) between takes. And, as this film was made long before computer graphics, some scenes, such as a striking sunrise, simply required luck, early morning setup, and patience, in order to capture the cinematic magic.
The movie is about skin color and fitting in, and about compassion and mercy. It also explores the ambiguity of motives, such as the conflict between political expediency versus personal morality.
It's interesting that the movie works and was successful without any love interests or indeed any women in speaking roles at all. (I didn't notice this fact while watching; I only read about it later.)
