Love sublime says the title. Another blurb during the promotions of the film talked about inner vs external beauty. Well in this case the beauty - you decide inner or external - is provided by scantily clad (or is that scantily dressed/ undressed) Zeenat Aman who the director Raj Kapoor called "a volcano of talent" while the film was being made. One can't accuse him of sarcasm of course - after all he was promoting his own film.
The paper thin plot is about a woman with a disfigured face who has a - er - well proportioned body , a great voice (thanks to Lata Mangeshkar) with whom the hero Shashi Kapoor falls in love. He doesn't want her face only her voice. The acting is desperate and even the 4 is because of the music with Lata Mangeshkar giving some good numbers. The rest is of course bunkum. Avoid - save your money. Inner beauty vs Outer beauty. !!! You need not be an Einstein to figure out which one the director was concentrating on
