Yaadein (“Memories”) is a 1964 B&W Hindi film directed and produced by Sunil Dutt also starring himself. The only other actor in the film is Nargis Dutt, that too as a silhouette in the final scene.
This film is the first of its kind as it features only a single actor and hence has found an entry in the Guinness Book of World Records in the category of “Fewest actors in a narrative film”.
Film narrative progresses through dialogues and background music composed by Vasant Desai, who also gave the song, Dekha hai sapna koi.. (sung by Lata Mangeshkar.)
The film is soliloquy of a man who comes home to find that his wife and son are not at home, he assumes that they have left him and reminiscences his life with them, and scared of his life without them, he regrets his past indiscretions. The suspense is only revealed in the end.
