LONDON, England (CNN) -- Representatives of the parents of missing toddler Madeleine McCann are in talks with a production firm about making a documentary following the ongoing search for their daughter, a spokesman said Tuesday.
Madeleine McCann disappeared May 3 from the family's hotel room in Praia da Luz, Portugal.
Discussions are at "a very early stage" but the production would be an "observational documentary," Jim Gallagher, a spokesman for the talent and entertainment agency IMG, told CNN.
Gallagher said program maker Darlow Smithson -- owned by IMG -- had held "a preliminary meeting" with representatives of Gerry and Kate McCann, whose daughter went missing in May last year from the family's holiday apartment in Portugal.
The McCanns were named as official suspects in September by Portuguese investigators.
They deny any involvement in the disappearance, saying they believe Madeleine may have been abducted by pedophiles and taken to North Africa.
"Discussions are still at a very early stage and the issue of money has never been raised," Gallagher said.
He gave no details of whether the planned production was for television or film.
IMG is the world's largest talent and entertainment agency. British production firm Darlow Smithson's previous credits include "Touching The Void," an award-winning drama-documentary about the fight for survival of two British climbers lost on a mountain in the Andes.
The May 3 disappearance of the British child made headlines around the world. Her parents said she disappeared from their hotel room at a resort in Praia da Luz, Portugal, while they dined in a nearby restaurant.
Her parents embarked on a high-profile campaign to highlight their daughter's plight, traveling throughout Europe and Africa.
Despite a search stretching around the world and the support of celebrities like Virgin Chairman Richard Branson, author J.K. Rowling, and soccer star David Beckham, there have been no major breaks in the case.
In December, the McCanns released a Christmas appeal for people who know what happened to come forward.
In the video that showed Madeleine opening presents, Gerry McCann said it would be "the hardest Christmas imaginable", and the girl's mom sent a message to her: "We all miss you so much. We are doing everything to find you." E-mail to a friend
