I have seen this movie 2 times. It is superb. When I saw this movie for the first time 29 yrs ago, I couldn't recognize Helen because she looked different in each scene of this movie. In one scene, she would have black hair and in another scene, she would have brown hair or reddish hair. I seriously thought they were all different women because of their different hairstyles. It turned out they were all actually Helen. She was very fashionable and gorgeous here. Rajesh Khanna and Tanuja acted well. This movie was made around 1971 during Rajesh Khanna's height of fame. Reportedly, he was late to the sets of this film. Bindu had a small role here but she acted very well. One thing I didn't like about this movie was the length of this movie. It could have been reduced without the unnecessary comic side-plot. Other than that, I recommend this movie.
