Sanjay and Milan Luthria's friendship goes back a long way in time.
Sanjay as we all know had taken out time from his busy schedule to do the dubbing for Taxi no. 9211. When the reports of the great response that it has received at the box office reached him, he promptly called up Milan to say, "I am so glad that your film is doing so well. I am really happy for you."
He further added that, "You are really a fabulous director and wish all the best." Now that's what we call true friendship.
