Other details about his role in Imtiaz Ali's project are still not out. He has featured in projects like "Befikre" and "2 States".
"I wasn't jittery at all. I have worked with a few stars and working with Shah Rukh Khan was a great experience," Aru said in a statement.
He added: "Sometimes actors tend to fade out from the surroundings. That happened to me and I suddenly looked to my right and gasped 'Shah Rukh Khan', I literally had to remind myself, 'You are doing a film with him so relax'. In fact I have grown up watching his films."
Aru, who will also be seen on the TV show "Drama Company", says working with Anushka was also an "absolute pleasure".
"She is very down to earth and very particular about her acting. The good thing about her is how she can switch off and on between takes, it's very endearing to watch. It was a big learning curve for me to work with such artistes...," he added.
"Jab Harry Met Sejal" is releasing on August 4.
