It has been 50 years since the movie release and ever since then the movie has held its popularity as a cult classic over the years. The 2019 remake starring Siddharth Malhotra and Sonakshi Sinha is a testament that the plot line is still relevant and still popular.
The movie revolves around a painter - Dilip Roy who has been convicted for the murder of his wife and is on the run from the mental asylum, he takes refuge in a lone house where a women is waiting for her husband who is expected to arrive later in the night. As the night progresses, the chemistry between the fugitive and the female evolves before secrets tumble out of the closet.
Despite multiple reruns, I still get impressed with the chemistry between Rajesh Khanna (Dilip Roy) and Nanda (Mrs. Jagmohan) and how Yash Chopra (the director) managed a script that breaks the stereotype of a murdered and her counter. Full marks to the supporting cast which involve many senior artists that make full use of the meaty plotline. The background score is scary and does full justice to the plot.
