The families of the 12 boys rescued from a cave in Thailand have not yet signed lucrative movie deals, as is being reported in Hollywood and Australian press outlets.

A special "Creative Media Committee" has been established by the Thai Government to negotiate any deals with the families, and this week it put out a fresh call for applications.

The ABC checked with the Thai authorities and parents on Wednesday, and they confirmed no movie deals had been approved.

"We haven't signed any movie deals," Adisak Wongsukchan, the father of 14-year-old Ekkarat Wongsukchan ("Biw"), said.

The dramatic rescue of the 12 soccer players and their coach gripped the world in July, and there has been keen interest in re-telling the story.

The Thai Government has repeatedly denied a movie deal has been secured, after a September 17 article in the Hollywood publication Deadline.

"Universal Pictures has acquired the life rights of the divers and survivors of summer's Tham Luang cave rescue in Thailand," reported Anthony D'Alessandro and Anita Busch in the Deadline story.

"CAA agent Matt DelPiano was instrumental and led a team effort, traveling to Thailand and Australia to secure the life rights for those involved including Wild Boar team Coach Aekkaphol Chantawong, divers Dr. Richard Harris and Dr. Craig Challen, and the players on the Wild Boar soccer team," the article said.

The families have each been offered $US11,500 ($15,859) for the option of making the movie, a further USD$115,000 ($158,572) once filming starts and a series of box office bonuses if the film meets certain profit targets.

However, they have been told not to sign anything without Thai Government approval.

Fairfax media this week reported the two Australian divers who played key roles in the rescue will receive US$1 million ($1.37 million) each for a movie-and-book deal with Universal Pictures and the publisher Ballantine.

"Richard 'Harry' Harris and Craig Challen, who were instrumental in the rescue of the Wild Boars soccer team in July, have verbally agreed to the deal," Fairfax reported.

The Thai Government said there were now 22 films, a TV series, animated games, music videos and books underway about the dramatic rescue, as well as 27 requests for media interviews.

The rescued members of the Wild Boars junior football teams have already travelled to the United States to appear on the Ellen television show and to Argentina to attend the 2018 Summer Olympic Youth Games.
