The 46-year-old has teamed with Katrina, 28, and Anushka, 24, for Yash Chopra's yet-to-be-titled film.
"It's been a learning experience, it helps me. It's wonderful to work with actors who come with a new language and a new way of doing scenes," Shah Rukh said Monday at an event here.
"The other day I was in Yash Raj Films (YRF) and I was told by my director that you have acted differently. This is one of the biggest compliments because I have worked with younger actors. I had a great time," he added.
He said it's been "a pleasure, honuor and wonderful experience to work with Katrina and Anushka Sharma".
While it is the first time Katrina and Shah Rukh have been paired, Anushka made her Bollywood debut with SRK-starrer "Rab Ne Bana Di Jodi", under the YRF banner.
