Vladimir Petrov - Pyotr pervyy II AKA Peter the First [Part 2] (1938)

DVDRip from print restored by Mosfilm in 1965 according to the credits, it still looks grey. After having read the descriptions below I found it be easy to follow the film without subtitles, the acting, the mise en scène and the cinematography are excellent. There is very little music though, two or three church choruses and folk songs, bits of post romantic orchestral music here and there. And, as been said below, no obvious propaganda.

IMDB user Denis888 from Russia (slightly corrected): Forget about the terrible Stalin's purges that were going on in the Soviet Union when this film, or rather its first episode, was shot. The film has none of the Stalinist propaganda or dull Soviet ethics. This is a great, bright and powerful work. The role of the great Russian tzar Pyotr I is played by a brilliant Nikolay Simonov and he did a wonderful job. His Pyotr is wild, often terribly cruel, loud and unbearably ferocious to his enemies. He never hesitates and he breaks through like a wild bull. The first episode tells about the terrible beginning of the Northern War with Sweden, the Russians are shamefully defeated and thus the tzar starts his bloody reforms. He reorganizes the weak old army, he takes down the church bells for military purposes, he is even ready to arrest his own weak and sickly son Aleksey who is in fact his terrible rival. The second excellent role here is Aleksander Menshikov, the tzar's favorite aid, played by an enigmatic Mr. Zharov. His part is cute, sly and so great that it provokes a grand smile. The first episode is also about the first military victories, the beginning of the Russian fleet and the foundation of the city of St. Petersburg, exactly 300 years ago...

Grigori Chukhrai - Ballada o soldate AKA Ballad of a Soldier (1959) - (DVD)

Amazon.com:
Grigory Chukhraj's poetic odyssey of an accidental hero on a six-day pass is a sentimental journey through the ideals of the Soviet state in World War II. Vladimir Ivashov is the fresh-faced signalman whose trip from the Russian front to visit his white-haired mother becomes a series of detours as he stops to help the loyal comrades, fellow soldiers, and salt-of-the-earth civilians (as well as a few shirkers and scoundrels) he meets along the way. On a transport train he even falls in love with a pretty young stowaway, a feisty blond girl-next-door on her way to visit a wounded boyfriend. Delicately photographed and gently paced, this deliriously romantic road movie is undeniably Soviet in its celebration of patriotism and collectivism, but Chukhraj transcends politics with delightfully vivid characters and a deft mix of comedy, melodrama, and romance. --Sean Axmaker
