The 29-year-old actor, who made his debut with two other actors- Alia Bhatt and Varun Dhawan- in the Karan Joahr-directed film, is happy to do a solo lead this time.
"This is the real test for me. I am really excited to be doing a solo film, I am on my own. And I hope I will not disappoint people. More than nervous and excited, I feel more responsible now to entertain people. It is on me now," Sidharth told PTI in an interview.
'Hasee Toh Phasee' is a romantic comedy directed by ad-filmmaker Vinil Mathew and produced by Johar and Anurag Kashyap. Besides Sidharth, the film also features another rising star Parineeti Chopra.
After being directed by Johar in his very first film, Sidharth said working in a movie helmed by a newcomer was a very different experience for him as he felt more pressure.
The actor said he and his co-star Parineeti hit it off right from day one - all thanks to their Punjabi background and shared love for food.
"We are in the similar age group, we were launched the same time, so we hit it off from the first rehearsals. We both are North Indians, Punjabis, outside the industry, foodies. And she is very easy to get along with," he said.
