Make-up artist Preetisheel Singh, who has worked on the looks for Amitabh Bachchan and Rishi Kapoor in their upcoming film '102 Not Out', says the dedication and focus of the veteran actors even after so many years of professional life is "awe-inspiring".

Singh has done heavy prosthetic make-up for the two in the film, and it was quite time-consuming.

Talking about her experience, Singh said in a statement: "Even after all these years in the business of entertainment, their child-like enthusiasm and devotion to their art is awe-inspiring. Their energy and intensity are infectious that one can compare it with the current heartthrobs."

"They would chip in their bit with interesting suggestions and even after the meticulous time spent for their makeovers, the team would always find them smiling when their shots were ready," she added.

In the film, Big B plays a 102-year-old father to Rishi, who essays a 75-year-old.

According to Singh, "Creating that age disparity was a task but it gives me great satisfaction that the makers and actors are happy with the outcome."

Produced by T-Series and directed by Umesh Shukla, the film is based on a Gujarati play of the same name.
