"Instead, it was very comfortable," for Ali.
"She is easy going and there was no awkwardness that she is a married woman and such a senior actress. Maybe it was because of the workshops that we did together before we started shooting," he added.
Ali will also be seen in a song and dance routine with Vidya and "there is a lot more than what you have seen in the trailer".
The film is slated for a July 4 release.
