The screening was held Friday.
Asked for his reactions on the comedy film, John said: "The movie was good. Genuinely I love comedies, I enjoyed the film so much. Ajay (Devgn) is brilliant, Abhishek is just outstanding and I am so happy seeing him in the film because he really made me laugh."
Abhishek indulged in some 'dostana' with John.
"He (John) is biased about me. He is my jiggly-poo right... and so I am biased towards him as well. I am very happy he saw the film," said Abhishek.
The duo are excited to be seen together once again in the sequel to their 2008-hit "Dostana".
"We are waiting for (writer-director) Tarun Mansukhani to finish the script. We will go and ask him about it and when can we start shooting for it," said Abhishek.
"But we are excited, the boys will be back," added John.
