Filmmaker Karan Johar feels actress Alia Bhatt has done a wonderful job in multi-starrer period drama Kalank, and says he got emotional after seeing her performance.

"I saw something that Alia had done in Kalank and I was just so moved by the work she had done," Karan said in a statement.

"I won't disclose what it is (but) she has done something in the film. You know when I see Alia I get that feeling like I'm seeing my daughter perform. And because I have that emotion for her I just started crying in the end for some weird reason. I'm going through something internally which I'm not aware of and I just got very teary. And I rang her up and said her I got very emotional, well done," he added.
