Мосфильм (Mosfilm, https://www.mosfilm.ru/main.php)
Mosfilm is one of the largest and oldest film studios in Europe. The studio was established in 1923, and by the end of the Soviet Union had produced over 3,000 films. They’ve put many of them up on this website, including works by Sergei Eisenstein and Andrei Tarkovsky, or even adaptations of books you might read in literature classes, like Anna Karenina or War and Peace. Aside from the large variety of types of films, they also have pictures of old posters, sets, costumes, and cars that you can sort through. This website is great if you want to watch films of varying topic or Russian-language difficulty, and also good for learning about Soviet culture and Russian film culture.
