"Salman is my mentor and I am here because of him. It was not difficult to have him in my second film. I genuinely respect him. I have a relation with him which is like we will be friends till our last breath. Whenever I am in trouble I think of Salman," Prem told PTI.
Prem, who recovered from cancer recently, says Salman was very much concerned about his health.
"No one from Bollywood was there by my side as I don't know much people here. I am close to Preity and Salman. They both know everything about my life. They are my genuine friends," he added.
Post illness, the filmmaker now wants to spend more time with family. Prem's father passed away last year. He reportedly flew to UK in September-October last year for surgery while battling gall bladder cancer.
