Aishwarya Rai Bachchan is all set to the footsteps of her father-in-law Amitabh Bachchan. Big B played the role of a 13-year-old kid suffering from progeria for his Balki directed movie with an amazing transformation through prosthetic make-up. Now, Ash in her upcoming Vipul Shah movie Action Replay, is going through an equally complicated makeover to look like an old lady for some scenes.

Seemingly, even Ash is being given her look by famous Hollywood make-up artists and the process takes between 4-5 hours. While Amitabh's Auro was perfected by Christien Tinsley (The Passion of the Christ) and Dominie Till (The Lord Of The Rings trilogy), Ash is getting help from Paul Pattison who has earlier styled Mel Gibson for Braveheart and Tom Cruise for Mission Impossible.

A close hand discloses, "The movie is most perhaps about time travel and Ash will be seen playing an old lady in a portion of the film. She had to patiently give over four hours to get the desired look -- which took many prior sittings just to be finalized. It was an everyday nightmare to first put on and then remove the make-up. Bachchan too went through a similar experience. But Ash was on time regularly for these sessions."

Vipul Shah confirmed the news and told, "Ash is playing an old lady in a portion of the film and she did have to spend around 4-6 hours everyday for the make-up, but she was extremely cooperative. It's a look people have never seen her in before -- it's our USP and a big secret."
