The 29-year-old says after the success of his first movie, he felt a lot of pressure doing "Hasee Toh Phasee".
"There is definitely pressure from the business point of view. After 'Student of the Year' I have become more responsible, more aware about what is happening around. I guess I have improved as an actor, both in terms of quality and quantity, in terms of performance," Sidharth told reporters during a promotional conference here.
Sidharth says his latest movie is completely different from a typical Karan Johar movie.
"'Hasee Toh Phasee' is completely different from a typical Karan Johar film. We had a restricted budget, there was nothing like luxurious cars or anything. We used to pack up early, there were restrictions. I realised how spoilt I was in 'Student of the Year', but it was quite exciting," Sidharth told reporters during a promotional conference here.
Talking about his character in the movie Sidharth said: "He is lost, not successful and sentimental. He is not a typical hero kind of character. He is under pressure and is the most stressed out character of the movie."
