New Delhi, April 4 (PTI): Emraan Hashmi says the story of his upcoming film "Mr X" calls for sequels but the possibility of a franchise will depend on its success at the box office.

"Mr X", also starring Amyra Dastur, is a sci-fil movie that centres around an Anti-Terrorist Squad officer (Emraan), who undergoes a life-altering accident, which brings him face-to-face with his invisible powers.

"The film has been designed to have a long run like 'Mr X 1', 'Mr X 2' and so on... but the final decision will depend on the box-office success of the first film," Emraan told PTI during a visit here.

The 36-year-old actor clarified that his character in the film is not a superhero.

"Many people are misconstruing it as a superhero but I will not put Mr X in that space. Whether he becomes like that will be known if there is a trilogy. Mr X is not a superhero because if I compare him Batman, he would still think before killing Joker but Mr X won't think before killing someone," Emraan said.

The star, however, admitted that it is his first righteous character with just a little tinge of "grey".

"This is the first time I am doing a family entertainer and before this I have always played devious roles. Mr X is a righteous ATS officer, he works for the anti-terrorist cell.

He goes through a very traumatic incident, which almost kills him then he rises from the ashes and he has a kind of ailment where his cells stop reflecting light.

"This ailment becomes a boon later and he realises he has superpowers. But he is not using them to save humanity. In that way, he is still a little bit of grey. If he becomes a society saviour in the coming parts, is yet to be seen but in this film, he is in revenge-seeking mode," Emraan said.

Produced by Mahesh Bhatt's Vishesh Films and presented by Fox Star Studios, "Mr X" releases on April 17 in 3D and 2D.

The actor is particularly excited for "Mr X" because he feels he can show to his five-year-old son Ayaan.

"My wife has always kept my son away from my films, not that he can understand much but now he probably can understand more than he used to... so yeah 'Mr X' will be the first film I can show it to him. He is very keen to see it because my character has superpowers.

"I was always anxious to show my movies to him because he has many relevant questions as a five-year-old. When he would see his father holding a woman on screen, he would think he has ten other moms out there. 'Who's that?' he would ask. So, we will cover up his eyes when a kissing scene comes.
