How was Dharmendra responsible for delays in Sholay?

The foundation for one of India's biggest films Sholay was laid in 1973 in October after several rounds of talks and casting, but when the film went on the floors, Dharmendra, to further his romance with Hema Malini caused delays in shoots.
 

The sets of Sholay and scenes with Hema Malini was used by Dharmendra to woo the actress more than complete the shot at times. The actor who fell for her during their previous encounter in Seetha Aur Geeta was responsible for delays.

For the world, it looked like the romance was onscreen, but only the three; Dharmendra, Hema Malini and director Ramesh Sippy, knew it was more than that.

Years later it was revealed that Dharmendra also paid light boys to drop and distract the shot which led to many retakes and gave Dharmendra a chance to spend more time with Hema Malini.

After the release of Sholay in 1975 on Independence Day, the love that began during Seetha Aur Geeta became stronger, as it earned the actors more name and fame. 5 years later they ended up getting married.
