The long-running negotiations over film rights are getting closer to a deal, according to two sources with knowledge of the talks, who asked not to be identified because of possible reprisals from the Thai Government.

The ABC understands representatives of two competing film companies will meet with family members on February 25 to discuss their offers.

The 12 players and coach of the Wild Boars Football Academy became international celebrities after their dramatic rescue from a flooded cave in July.

While an American agent has touted verbal agreements between several key players in the rescue and Universal Studios, no formal deals have been completed with the boys' families.

On advice from the Thai Government, the families have registered a company called Thirteen Tham Luang Co Ltd, with coach Ekkapol Chantawong appointed as the director.

"From now on every deal has to go through this company," a source close to the negotiations told the ABC.

The Thai Government has suggested appointing a well-known beauty pageant winner as a negotiator for the families.

The Government has been contacted for comment.

A Thai-language movie has already finished shooting and is scheduled for released mid-year, and National Geographic has been filming a documentary at the cave.

Government pressured parents to let boys travel

Since the rescue there has been high demand for the members of the Wild Boars team to appear at international events.

The boys travelled to Argentina for the Youth Olympics, to the UK for a morning TV show and to the US to appear on the Ellen show.

However, the ABC has been told the Government handling of the trips has left some families unwilling to travel again.

"Some parents don't want their kids to travel because they don't know the details of the trip," a source with knowledge of the travel arrangements said.

Following the UK and US trips, the parents joined together to tell a Government-created "creative committee" they wanted the boys to stop travelling to foreign countries and instead focus on their schooling.

But in the following days a member of the committee phoned individual parents and convinced several to let their boys travel to Dubai.

The ABC understands the Government has a list of 17 other international requests for possible appearances, including a trip to Australia.
