Mehboob Khan, who directed Aan, Andaz and Mother India, also made this unusual film. It explores themes that were avant garde for the 50’s: a man’s sudden succumbing to sheer lust, while being in love with another woman; a woman’s sympathy for `the other woman’; a villain who’s shades of grey rather than totally black-hearted. Not exactly standard Bollywood fare. There are clichés of course, but on the whole, this is worth a watch.
