Emraan Hashmi's son Ayaan has now turned five. While he loves his father and has loved movies since he was born Emraan chose not to show him his earlier films due to kissing scenes. Mr. X' is a family film, where Emraan plays an invisible man (a vigilante who takes up the law in his hand only to protect it). Ayaan has been a big superhero fan and believes that there actually exists a Batman in real life.

Ayaan had fortunately been early detected for cancer as a result of which, he is now completely cured and is back to school. Emraan knows that his son will be the most difficult audience to please and that is why he is so anxious, as he knows that Ayaan's benchmark is obviously going to be Batman and that is unreal, asMr. Xis not a superhero film. But Emraan is hoping that seeing his father in his invisible avatar and that too in 3D, will hopefully get Ayaan's approval.
