Jha has also quashed rumours that his movie title was lifted.
"There is a (censor) board category dispute going on whether a U or a U/A certificate is to be given to the film. There is a difference of opinion there for the voting of the category of the film," Jha told reporters here Thursday.
"It is a difficult film and it took time to make it, so it will take some time for them (censor board) too," he added.
The 58-year-old slammed the claim by filmmaker Kamaal R. Khan that his movie title has been lifted. Khan has claimed that the title was registered under his name for he last five years.
"There is no problem with the title. We have it since the last nine years. We'll soon come out of it and everyone will see... it is just that someone is trying to cash in on our name," he said.
Jha was here Thursday evening at the PVR Cinemas, Select Citywalk, Saket, to promote the movie. Also present with him were the cast of the film Ranbir Kapoor, Katrina Kaif and Arjun Rampal.
"Raajneeti" also stars Nana Patekar, Naseeruddin Shah, Ajay Devgn and Manoj Bajpai.
