Mumbai: Actor Sidharth Malhotra and his co-star Katrina Kaif will wear prosthetics make-up in Farhan Akhtar's next home production in which they will play a couple ageing from 30 years to 60.
Both the actors have given their nod for debutante director Nitya Mehra's untitled love story.
"There are different age groups that we have to play in the film. I have to age as the character grows. I am playing a character who grows from the age of 28 to 46 to 60. And to play these parts is tougher for me. I am excited to try prosthetics look," Sidharth told PTI in an interview here.
"I and Katrina are trying different looks. We have a great prosthetics team from London Mark Hulio, who won an Oscar (award) recently. We have an A grade team in make-up and prosthetics," the 30-year-old actor said.
There were reports that the untitled film is a time travel movie, which Sidharth denied.
"It is not a period film.. It's not time travel. It is a journey of this couple, a love story that spans across different age groups," he added.
There will be changes in the look of both Sidharth and Katrina and he is okay with it.
The "Ek Tha Villian" actor said the international prosthetics make-up team has great technology of putting silicon mask, changing eye colour, hair.
"We are preparing for the film and have done enough workshops. We are quite excited to start it," he said.
On being asked if he feels a sense of nervousness to work with established stars like Akshay Kumar, Katrina, he said, "There is no nervousness in working with established stars as such. The film (Nitya Mehra's film) is way tougher because I have to play different age groups," he said.
