A movie on India's victory in the 1983 Cricket World Cup may be incomplete without at least one of the members who made the win a reality -- but filmmaker Sanjay Puran Singh says it's too early to comment on whether Kapil Dev or Sunil Gavaskar will be part of it.

"I am thrilled to direct this film on the 1983 Cricket World Cup. I wonder why nobody has still touched this space before. We are still working on the script and it will go on floors by the end of this year," Singh of "Lahore" fame, told IANS.

"The two prominent faces in this film will be inspired by Kapil Dev and Sunil Gavaskar. As far as Kapil and Sunil coming on board is concerned, it's too early to talk about it. This is not the right time to talk about it," he added.

However, a source close to the film said: "Kapil Dev and Sunil Gavaskar are on board. They are likely to do a guest appearance in the film."

The film is tentatively titled "1983", and it will go on floors by this year-end.

When asked who will be seen playing the then captain Kapil Dev in the film, Singh said: "I don't write the script keeping characters in mind, but my concern is that the actor who will come on board should resemble Kapil Dev."

India won the 1983 Cricket World Cup against the West Indies.
