Reena Roy (born 7 January 1956) was one of the top Hindi film actresses in India. She performed leading roles in many films from 1972 to 1985. Reena Roy's career in films started off with a non-starter, B. R. Ishara's Nai Duniya Naye Log with another newcomer Danny Denzongpa, but it was shelved temporarily. Undeterred, B. R. Ishara cast both actors again in Zaroorat (1972), along with another newcomer Vijay Arora, and the racy film got her some attention. She was now called the "Zaroorat Girl." Yet, she struggled for the next four years in B grade films that had feeble scripts and faltering leading men. The bright spot during this period came with her lively performance in Jaise Ko Taisa (1973), and her rain-soaked dance to the song "Ab ke Sawan" with Jeetendra raised temperatures.
