"I want to do a film on constipation. I've a fascination for constipation. I am working on the script," Sircar told IANS in an interview.
The genre is yet to be decided, but there will be a humour element in it, he said. "I don't know if it will be comedy or not, but it will be shown in a humorous way."
If his first movie, the critically acclaimed "Yahaan" revolved around Kashmir, Sircar offered a heavy dose of laughter in his successful movie "Vicky Donor", which talked about an issue like sperm donation.
The director likes to bring forward those stories that are interesting. His recently-released "Madras Cafe" is a spy thriller and he claims he has a knack for such subject. "I knew about the subject and I thought it is an interesting story that should be brought forward. That's how I worked on the script (of 'Madras Cafe')," said Sircar.
So far he might have stayed away from movies filled with glitz and glamour, but he said he won't mind doing it if the story is good.
"As long as it's senseless I won't do it. If glitz and glamour make sense, I'll do it for sure. But if it's mindless, I won't be interested. It should have a good story," he said.
Sircar has tasted success, but admits he is yet to crack the hit formula.
"I love to play with genres. I don't have a hit formula. I am also trying and testing," he said.
The filmmaker considers the script of his films to be the hero, but admits enjoying a good bond with John Abraham, the lead actor and producer of "Madras Cafe".
"While we were working on the script ('Madras Cafe'), the 'Vicky Donor' idea came up and we worked on that. After that we were ready with the script and we said let's move on and make the film. That's how the film came up and our partnership also went ahead," said Sircar, whose "Vicky Donor" was also produced by John.
"He doesn't interfere in my job as a creative person. For marketing, I depend on him as I know nothing about it... I hope to carry on and do more good films with John," he added.
The two certainly make a great team, but the director had put one condition in front of the well-built actor before signing him for "Madras Cafe".
"The condition of doing the film was that he had to look thin. I told him that he should look like a part of the crowd. He agreed and we moved on," said Sircar.
