The actress told IANS that it was a great opportunity to work with such an "experienced filmmaker".
"She is very intelligent. She treats every actor with respect. The film will be shown at festivals soon. I am proud that I am part of some interesting projects.
"I loved working with Mira. She is the best I have ever worked with. I have learned a lot from her as an artiste," said Richa.
The "Fukrey" star plays a South Mumbai "brat" in the short film, which also stars Oscar winning actor Ben Kingsley.
"The film is about people's relationships. It's little surreal," she said.
