I have watched this movie quite a few times, but I think its one of the rare movies I tend to watch with equal enthusiasm every time. Although, it was a remake of a Tamil film "Adhutha Vittu Penn", I thought the Hindi version was EQUALLY amazing and not to mention immensely entertaining =) I thought performance-wise Kishore, STOLE THE SHOW! I cannot imagine the movie without him. The guy is incredible at comedy. Sunil Dutt was fabulous, I just adore him to bits, he is so underrated...he put in a stupendous performance! ROFL gotta love the scene where he attempts to learn music from Kishore...he had me in splits. As for Mehmood, he simply rocked. 'Daaaaaai' bhola . I liked his unique accent. haha. I think its imitated by plenty of actors till date and yes, its annoying to the core. Saira, well I usually find her very irritating in most of her films, I thought she was passable. The soundtrack was amazing. Ahhh...man I can just listen to them all day long. My personal favorites include kehna hai, mera samne wali ladki ne and main chali is one of best female duets sung by Asha and Lata. The movie is a must watch, it's a classic in every sense. Highly recommended! 9/10
