"Vicky Donor" is a light-hearted take on the taboo attached to infertility, sperm donation and artificial insemination.
"I am happy with the kind of response 'Vicky Donor' has got. While writing the script, me and my writers thought we will get a positive response from young boys and girls, but with the film becoming so popular among the masses, it feels great, " Sircar told.
"I never thought my film will get a U/A certificate from censors. It came as a shock for me. The success of the film is the biggest example of audience getting mature. I personally feel that the audiences are very clever and they know what they want to see, " he added.
Co-produced by Eros International and JA Entertainment, the film was released Friday over 600 screens worldwide. The film, which was made with two newcomers - Ayushmann Khurrana and Yami Gautam - along with seasoned actor Annu Kapoor, has grossed over Rs.11.40 crore in India and Rs.2 crore overseas.
"We are very happy with the audience as well as critics' reactions to 'Vicky Donor'. Sunday's collections showed a 91 percent jump over Friday figures, " Nandu Ahuja, senior vice president, distribution, India, Eros International Media Ltd said in a statement.
"The film created a positive buzz right from the launch of its trailer and has delivered on audience expectations. With its unusual subject, characters and dialogues, we are hoping for repeat viewings and a promising run at the box office, " he added.
Trade analyst Taran Adarsh says "Vicky Donor" success proves that content is king.
"The success of "Vicky Donor" is the triumph of its story. The script of the film is the real hero. Every character, be it Ayushmann or Kamlesh Gill or Yami, has fitted so beautifully in the film. I give full marks to the script.
With a taboo topic, new actors, a small budget, the kind of business the film has done is commendable, " Adarsh told.
"Films starring newcomers or lesser known actors don't find a theatrical outlet in the international arena. The success of 'Vicky Donor' should also encourage distributors to go beyond the boundaries of India and explore newer horizons, " he added.
