Sridevi and Sunny Deol in Nigahein (1989)

Sridevi and Sunny Deol in the fantasy thriller Nigahein (1989). She looks so, so gorgeous in this movie. As one of the first few sequels ever to be made in Bollywood in the 1980s, the makers tried to cash in on the stupendous success of Nagina. 

Expectations were so sky-high (especially as the movie was released in the same year as Chandni and Chaalbaaz) that the producer and director locked in a third part for the film - to be titled Nagme. Sadly, due to the under-performance of Nigahein (and a whole glut of snake-based films that all tanked around the same time), the idea was scrapped.
