(CNN) Bollywood star Irrfan Khan, known internationally for his roles in "Life Of Pi" and "Slumdog Millionaire," died Wednesday, his representatives confirmed. He was 53.

"It's saddening that this day, we have to bring forward the news of him passing away," read a statement from Khan's PR agency, Hardly Anonymous Communications. "Irrfan was a strong soul, someone who fought till the very end and always inspired everyone who came close to him."
