The last movie Stalin watched before he died https://www.svoboda.org/a/24204619.html was a racemixing cuckold fantasy called Circus - one of his favorites.
It tells the story of a fictional American woman with a half-black baby who escapes evil Yankee racism by fleeing to the USSR, where she is embraced with open arms. The movie climaxes with a lullaby sung to the baby in various languages by every ethnic group in the USSR. It concludes with the American woman marrying an ethnically Russian man and also features a black soviet soldier with a Russian wife.
Circus won a first class Stalin Prize and was the USSR's most commercially successful movie.
Some additional sources stating that Circus was one of Stalin's favorite movies, for those who doubt the Svoboda article.
