"I feel that I learn something from every film. My motto is... it's not about perfection, it's about progress. I don't need to be perfect right now as long as I am progressing, improving and adding stuff film by film, year by year," Sidharth told IANS over the phone from Mumbai.
The four-film-old actor is currently basking in the success of his latest film "Brothers", which features him and Akshay Kumar as warring siblings. The action-packed family drama, which released on August 14, collected Rs.72.6 crore net at the box office in its first week.
Before that, he displayed his craft in films like "Hasee Toh Phasee" and "Ek Villain".
He is geared up to be seen as a brother of another actor on the big screen.
"Fawad Khan and I will be seen as brothers in 'Kapoor and Sons'. We are not competing in the film, but for now I can just share that both of us are writers," he said.
Sidharth, who has roots in Delhi, is working with the Pakistani star for the first time. And he's loving it.
"A majority of the film was shot in Coonoor. Since we had nothing else to do in Coonoor, we (Fawad and I) had lots of conversation about movies. We even played cricket. I had a great time working with him (Fawad).
"Culturally also, we were connected...where he comes from... Lahore is similar to Delhi. It will be great to visit Pakistan and see the country. He was kind enough to invite us also.
"Let's see if it works out and if time allows, I should plan something and go and meet my on-screen brother there," said Sidharth, who is positive about the film's release in Pakistan, where Saif Ali Khan's forthcoming movie "Phantom" has been banned.
Sidharth believes "Kapoor and Sons" is an "endearing film".
"This one ('Kapoor and Sons') should release in Pakistan. It's a sweet, family comedy and drama film," said Sidharth.
He is also looking forward to filming his next co-starring Katrina Kaif.
"We will start filming next week. It's a concept-driven love story where you show these two people (growing) over a period of time. It is very exciting to try all characters in the film... be it younger or older or my age," he said.
He even shared that once he wraps up filming the love story, directed by Nitya Mehra, he will "move on to something else in the action space".
Just a month back, he was seen donning the khaki for one of the magazine's photoshoots. Would he like to sport the look on the big screen too?
"The photoshoot was the first visual of me trying on a typical Hindi picture policeman which was almost like a surreal moment because I've seen these heroes wear it. So, why not? When I wore that uniform, I was excited. It will be interesting to play a policeman and put on the khaki.
"All the iconic heroes have done it and it will be fun too."
