Connections

Salman Khan refers to himself as the "Don" of the movie, while the theme song from Don is played.

Karan asks Kajol a question about the film.

The film is frequently discussed by the cast and background music is also played.

Don Ladla (Ashish Vidyarthi) sang part of the title song "Main Hoon Don" from the movie Don 2006. The title track music was also played in the background whenever Don Ladla entered a scene.

When Gaurav (Akshay Khanna) and Sheekha (Genelia D'Souza) were having coffee at the mall, the song "Khaike Paan Banaraswala" sung by Shahrukh Khan in Don (2006) was playing in the background.

The scene, in which Don is seen watching cartoons while in his bathtub, is an homage to Scarface which has a similar scene showing Tony watching TV in his bathroom

The scene where Don coldly kills the police informant in his gang using a forceful golf shot, is an homage to The Untouchables where Capone nonchalantly gets rid off a traitor with a baseball bat

The protagonists of both films, Eric (The Crow) and Don, have several similarities in their personalities. Both are ruthless, dark characters who are 'back from the dead'. Both advocate to "Quit smoking, as it kills" and are trying to quit themselves too. Don convinces Roma that he is Don by speaking a line familiar only to her just like the "Can't rain all the time" line spoken by Eric to Sarah.

The hospital sequence when Don wakes up from his medically-induced coma and kills his lookalike.

the shot of a floating Shahrukh in the song "Main Hoon Don" is taken from Gladiator
