Though "Boom" was a box office dud, Katrina's was noticed. Since her debut, the 30-year-old has given numerous hits -- "Namastey London", "Welcome", "Singh Is Kinng", "Raajneeti", "New York" and "Jab Tak Hai Jaan", among others.
"Today, she (Katrina Kaif) has become such a big star and has reached the number one position in the industry. It feels good. This shows that hard work and perseverence can get you in right place," Kaizad told reporters Monday on-location of his next film "Jackpot".
"Why not, I will work with Katrina? Definitely I will, if I will get the right script," he said.
When asked whether he is in touch with his discovery, he said: "Not really. If I will have a movie, I will get in touch with her. It's like that. I don't like to stay in touch just for staying in touch."
Kaizad, who is returning to direction after nine years with "Jackpot", met Katrina during the latter's modelling days in London.
Remembering that time, Kaizad said: "When I met her (Katrina), I said: 'You come to Mumbai and you will be a big star.' But it took her six months to come to Mumbai because she didn't know how to speak in Hindi and all," he said.
"I knew that when I will cast her, she will leave her impression... I was just the catalyst, rest is her hard work," he added.
