Monteiro, who played the role of Harleen Kaur in "Love Aaj Kal", has been cast despite her limited knowledge of Hindi.
"When I was looking for Aishwarya I wanted a face which made you say wish she was my love. Geselle has that quality. When we saw her at the auditions, this quality of hers came out in dollops. With her innocence and charm, she will make you fall in love with her, " said Abbas.
On her Hindi Abbas said: "It was a problem. She said if you change the lines I don't know what I will do. Don't change the lines and give me the script in advance. She had practised her Hindi a lot. She trained under a teacher to get the dialogues perfectly."
The movie based on the play Graffiti directed by Abbas is about four unique lives trying to compete with the pressures of growing up and the firsts that we all experience in school.
"The youthful music and the freshness of the film is surely its USP, " said Abbas. "I had done quite a few shows with Shah Rukh (Khan) and while doing the shows, I suggested that the play be turned into a movie. He agreed. I have cast fresh faces because I wanted to make stars than getting stars to act in my movie."
When asked to explain the title of the movie, the director said: "Today's teens think many things at one time. They always want to do them but only kabhi kabhi (sometimes) do them. They are always in love but kabhi kabhi they fight.
The essence of the title and the movie is 'kabhi kabhi jo dil kahe always wahi karein' (always do what the heart says sometimes)."
The cast Zoa Morani, Ali Fazal, Satyajeet Dubey along with Monteiro and Abbas were in the city to promote the movie and they had a rocking time playing the interactive game of sketch charade with the audience.
