Mumbai, Nov 24 (IANS): In retrospect, film producer Dinesh Vijan feels that investing more time on "Lekar Hum Deewana Dil" would have perhaps helped in favour of the film's box office performance.

The movie, which marked the Bollywood debut of Armaan Jain and Deeksha Seth, turned out to be a dud.

Asked what went wrong with the movie, Vijan said: "I think we should have spent more time on it...it was a learning experience. While the film was on post-production, I was abroad with the team of 'Happy Ending' and was simultaneously managing both the things. I don't want to blame anyone for this."

The film, which released earlier this year, was directed by Arif Ali.

Vijan was recently caught amidst reports of a rift with his business partner Saif Ali Khan. But he says they share a happy and a healthy relationship.

"I know Saif for more than 10 years and our bonding is very strong. (Only now) The films that we want to produce together, we will do it together and the films that I want to produce on my own, I'll produce it separately."
