Emil Jannings delivers a remarkable performance as an older man chosen by a Hollywood director (William Powell) to play a Russian general in a movie. Upon arriving on the set, he’s playfully mocked about a medal he's wearing. He then claims it was bestowed upon him personally by Czar Nicholas II, and after some lighthearted ribbing, his coworkers return the medal. The “General” glances into the mirror of his makeup box and is transported back to a memory of himself – General Grand Duke Sergius Alexander, cousin to the Czar and commander of Imperial Russian forces in 1917. His depiction of this dignified, capable man, who shows some practicality regarding their military circumstances alongside a tenderness toward Evelyn Brent (who is actually the Bolshevik spy tasked with eliminating him, "Natalie"), feels carefully considered and captivating. As the revolution shifts power against this formerly influential figure, we witness his character endure distress and humiliation before his new love assists him in evading a violent group. When the story returns to the present, this aging, fading patriot experiences one final surge of vitality... Although it may be rooted in reality – it was often safer for European generals who lost battles to flee than face repercussions at home – it’s ultimately a made-up tale, which I believe gives Josef von Sternberg considerable freedom to shape and develop the characters. Jannings is exceptional, although Brent also does well as the committed revolutionary who develops feelings for the old Duke, recognizing in him an alternate kind of devotion to his country—one she finds charming and admirable. The cinematography effectively portrays the revolutionary scenes set against a backdrop of poverty and cold, and the limited use of inter-titles helps keep this powerful, emotional story flowing smoothly. It's a really good film.
