"In projects such as these, the remuneration is secondary. Luke and I have worked together for a long time, so when he came up with this script, I found it very interesting.
"Also, I knew that he believed strongly in the film and would see that it gets its due, which is how I and Sandhya (Mridul) agreed to fully support him in his endeavour," Purab said.
"13th Floor" tells the story of two people who get stuck in an elevator and gain a new perspective in life.
According to Purab, the film was shot in six days flat, a feat he attributes to Kenny's sense of detailed organisation. The film has already got its share of admirers in the few previews that were held and Purab is confident it will not go unnoticed.
