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 told IANS.
Said 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.'
Sushmita and Govinda, who came together in 2002 fiasco 'Kyo Kii... Main Jhuth Nahin Bolta', are playing the main lead in this film too.
Sushmita, who is currently busy with her home production 'Rani Laxmibai' and is not taking any outside projects, made an exception for Bhagnani and Dhawan. She's sentimental about the two because they fashioned her first hit 'Biwi No 1' with Salman Khan and Karisma Kapoor.
Apart from 'Do Knot Disturb', Bhagnani is also launching his son and has roped in director Vivek Sharma of 'Bhootnath' fame to direct it.
'I'm simultaneously launching my son Jackie in Vivek Sharma's 'Kal Kissne Dekha'. While he will be shooting it in South Africa, I'll be with David and the crew for 'Do Knot Disturb' in Delhi.'
Bhagnani doesn't want to be looking anxiously at his son's debut. 'I'd rather be with David, Govinda and Sushmita,' he said.ALSO READ: Hrithik Roshan's Kabir returns in YRF spy universe with 'Tiger 3': Reports
