Since long both the actors have shared a very strong rapport with each other. While Sanjay acted in ALL THE BEST for Ajay, Ajay in turn gave ample dates to him for his home production RASCALS. This is just one of the many instances.
What we hear latest is that Sanjay has done voice over in Ajay's latest live action animation film TOONPUR KA SUPERRHERO produced by Krishika Lulla and Kumar Mangat. When Ajay approached Sanjay Dutt to do a voice of God, one of the characters in the movie, Sanjay Dutt immediately agreed without giving a second thought.
Kireet Khurana, the director of the movie said, "We wanted someone impressive for the voice of God to introduce the characters in the film. Coincidently, Ajay and Sanjay were shooting together at that time. When I asked Ajay if Sanjay would do it, Sanjay said 'Anything for Ajay'. He dubbed for us last afternoon."
