The film was earlier titled "Mehrunissa", but now it has been renamed "Pehle Aap Janab".
"The film is set in Lucknow and I want to shoot the major portions there. Besides, a set will also be created. I come from Lucknow and the film will be a tribute to the city of Lucknow," Mishra, who is co-producing the film with Shahnaab Alam, told.
He added: "It's a very funny place where people even abuse with a lot of respect. Who says it is a city of nawabs, it's a city of professionals."
Sudhir says the script has been sent to Amitabh Bachchan and Rishi Kapoor.
"We have sent the script to Amitabh Bachcgan and Rishi Kapoor. It wil be a comedy and it will be very funny. It's about two people who don't talk to each other."
Nikhil Advani, who was co-producing it earlier, recently walked out of the project. But his exit has not affected the film at all.
Alam said that "the film will go on floors this year".
"We are working on the logistics. Once we get a clear picture, we will be in a better position to talk," he added.
"Pehle Aap Janab" features Chitrangada Singh in the lead role.
