Deepak Tijori stated "I wanted to work with Mahesh Bhatt. I went to narrate the film to him, while he was on the treadmill. He heard me for like 15-20 minutes and then he said, 'I did not enjoy it. Forget it.' I was like okay. As I went out, I saw Mohit Suri and K.D. waiting outside. Mohit was a kid, he hadn't started his career at that time. He must have been searching for his subject. I told Mohit, 'Just tell Bhatt saab to listen to me once! You go and see that film Out of Time and show it to him anyhow!'" Deepak then added how it was Anurag Basu who informed him after three-four days that it was Mohit who was attached to the same film. He added, "I felt so angry because I thought of the Bhatts as family. I mean, this is my second career, and this is my life. The first betrayal of my second career, and such a big betrayal. And since then, until today, he has never come in front of me and admitted that he betrayed me in this way. Zeher, his first film. It was my idea... If he had just told me what he did. What difference would it have made? I was working with Udita (Goswami) in Fox, so many times I wanted to tell her. But eventually, they got married and they are happy. I am happy for them."
