Bhagnani and Dhawan have earlier given hits like Hero No 1 and Biwi No 1.

"It (Do Knot Disturb) is an out-and-out comedy. Let's not pretend about that. But it is an original idea and script. When David and I come together, we can't fool around with people's expectations," Bhagnani said.

Added Dhawan: "When Govinda says he has full faith in me, I get frightened. Will I be able to deliver again this time? I can't say our film is spectacularly different from what we've done so far. But at the same time I must admit audiences want to see something different.

"Look at Jannat. Its success is so welcome. But I can't do something too different with Govinda because I can't play around with audiences' expectations."
