Their last big release together was the 1974 Prakash Mehra film "Haath Ki Safaai", in which they played long-lost brothers. But then they also shared screen space in "Aakhri Daaku" in 1978.
Prabhu Deva says the duo were a natural choice for his film.
"Since I am launching Kumar Taurani's son (Girish Kumar) in my film, I wanted to cast a strong supporting cast. Randhir Kapoor and Vinod Khanna were my natural choices for two very important roles in the film," he said.
