The actor says his aim is to work hard and do justice with his characters.
"I had worked really hard for 'Byomkesh...' but it didn't open well on Friday. Saturday-Sunday was bad. By Monday morning, I was completely okay. I didn't force myself to feel normal," Sushant told PTI.
"With 'Dhoni...' the weekend was massive. But by Monday, I was fine, normal. I thought why is it like this, I should be flying. But I realised, I can't screw up next six-eight months of my life being obsessed about that weekend," he adds.
Sushant says though actors are generally typecast according to the kind of roles they essay, he does not give too much importance to these things.

"We do typecast actors like he is an action hero, he is a comedian. I don't care about it. It's not my headache, it's theirs (audience). With every film, the audience has to change the perception so I am not bothered by it," he says.
"From the day I sign the film, till I dub, I never think about anybody else. It's a very selfish thing. This is precisely the reason I became an actor," he adds.
"The role gave me an opportunity to show my martial arts skills. Shooting simultaneously for both the characters wasn't possible. So we shot for the contemporary one in Budapest then I took two and a half months break in between and prepared for the older character. I trained massively in sword fighting."
When the trailer was out, it was compared to SS Rajamouli's blockbuster "Magadheera" a love story which also had a reincarnation angle similar to "Raabta" but Sushant dismisses any similarity between the two films.
The film, directed by Dinesh Vijan, also stars Kriti Sanon and "Neerja" fame actor Jim Sarbh. It is scheduled to release on June 9.
