"There is a perception that the films that go to film festivals don't do business (box office collection). I think time has changed. The bifurcation is wrong (between festival and commercial films)," Rai told reporters here at the trailer launch of "Nil Battey Sannata".
Produced by Rai along with Eros International and Jar Pictures, the film is a tale of a single mother battling to ensure that her daughter gets every opportunity in life.
Directed by Ashwini Iyer Tiwari, the film features Ratna Pathak, Pankaj Tripathi and Ria, and it will be released in theatres on April 22.
Rai said he decided to come on board as a producer because he loved the idea of the film.

"Since childhood I have been following my heart and till today I follow what my heart says. I am happy being this way. I am proud of this film," he said.
Meanwhile, Rai remained tight-lipped about the film he is doing with superstar Shah Rukh Khan.
Tiwari, who earlier directed ad films, said she wanted to tell stories through films.
"The idea of the film came from my husband Nitesh (directing Aamir Khan's 'Dangal'). We worked on the story for a year," she added.
"The idea to do this film in Tamil came from Aanand sir and actor Dhanush. He (Dhanush) loved the film and asked me to direct the Tamil version. I was initially sceptical to do it," Tiwari said.
