Aamir Khan stated in an interview that his role in Dhoom 3 is the toughest role so far in his life.

Doom, a popular violent videogame, was a favorite of Eric Harris and Dylan Klebold, the teenage Columbine High School murderers.

In a chilling videotape they made before the massacre, Harris says It's going to be like fucking Doom .That fucking shotgun he kisses his gun is straight out of Doom!
