In an Q&A Christopher Nolan was asked about the late actor Irrfan Khan and it was then he confessed approaching Irrfan Khan for Interstellar.
Nolan said, “Yes. I did meet Irrfan for Interstellar. I was looking forward to working with him. Unfortunately, he wasn’t able to do the film. He was a great actor,”
Earlier, Irrfan had mentioned in an interview about why he couldn’t say yes to Christopher. He said, “They expected a huge commitment from my end. I wanted to be here for The Lunchbox and D-Day.”
