Nawazuddin said his learning on the sets of "Mom" helped him during the making of "Manto".
"While shooting I have seen how patient she (Sridevi) is as a person. Like even if the shot is after two hours she will wait patiently these are the things that you learn.
"I am working on "Manto" right now and it's a hectic and exhausting schedule but because of m'am I have learnt how to be patient," the actor said during the trailer launch of "Mom".
The 43-year-old said it was his dream to work with Sridevi and he immediately said yes to "Mom".
Produced by Zee Studios, Boney Kapoor and Sunil Manchanda's Mad Films in association with Thirdeye Pictures, "Mom" releases on July 7 in Tamil, Telugu, Malayalam and Hindi.
