Director Shoojit Sircar said that film's success proves that audiences have 'matured'.
"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," he told IANS.
"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."
Starring newcomers Ayushmann Khurrana and Yami Gautam alongside veteran actor Annu Kapoor, Vicky Donor was released on Friday on over 600 screens worldwide, grossing over Rs.11.40 crore in India and Rs.2 crore overseas.
Nandu Ahuja, senior vice-president of distribution at Eros International Media Ltd, India, said in a statement: "We are very happy with the audience as well as critics' reactions to Vicky Donor. Sunday's collections showed a 91% cent jump over Friday figures.
"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."
Trade analyst Taran Adarsh credited Vicky Donor's success to the strength of its script.
"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," he said.
"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."
He added: "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."
Produced by John Abraham, Vicky Donor addresses the subject of infertility and sperm donation.
