Chaalbaaz was one of the best comedies of the late 80s with some landmark performances from Sridevi in a double role , Anupam Kher as the evil uncle Tribhuvan Das , Shakti Kapoor ,Rohini Hattangadi and Rajnikant.The movie also has Annu Kapoor in a special role and a young Aftab Shivdasani as Sridevis young brother.It also won Sridevi a Best Actress Award for 1989.The " Jaani ye Chaaku hai" scene is legendary and unforgettable.A typical bollywood formula film with Twin Sisters separated at birth and with strikingly different personalities .Sridevi was the real " Hero" of the film .I remember I had copied it on my VCR as a kid and used to watch it everyday ! A most memorable film .
