Though four boys and their coach are still to be saved, American film crews have reportedly traveled to the rescue site in Chiang Rai to begin work on a movie telling the tale of the Wild Boars team, Australian website news.com.au reported.
The boys and their coach were trapped in the Tham Luan Nang Non cave that became flooded by monsoon rains while they were exploring it after a soccer practice June 23.
British divers found the 13, huddled on a muddy bank in a partly flooded chamber several kilometers inside the complex, on Monday last week. Major Saman Gunan - died during the rescue operation last week while trying to forge the escape path for the boys.
The last five were brought out of the cave on stretchers, one by one over the course of Tuesday, and taken by helicopter to hospital. For 17 days, Thai navy SEALS, divers and engineers delivered food, medical care and oxygen to the group while working to free them.
Two of the eight rescued so far have shown signs of a potential lung infection, but there is a hope they could honour the invite.
A crack team of foreign divers and Thai Navy SEALS has been guiding the boys out through almost 4 km (2.5 miles) of sometimes submerged, pitch-dark channels.
The freed children are all now recovering in hospital and were earlier reported to be in a stable condition. A local government official confirmed the rescue while a police source, who also did not want to be named, said "the ninth and 10th were about 20 minutes apart".
People across Thailand, and the world, have cheered the rescue operation, including at the Mae Sai Prasitsart school where six of the trapped boys are students.
The second group of four rescued on Monday are ages 12 to 14. "We would be honored to welcome the team from the Wild Boars Football Club and their rescuers to Old Trafford this coming season".
A few hours later, three ambulances, lights flashing, were also seen leaving the site.
Chief of the rescue mission, Narongsak Osottanakorn, declined to comment on the identity of the four people brought out in the evening, saying updates would be supplied at a news conference that is scheduled to be held late on Monday.
He said, "the kids are footballers so they have high immune systems".
Operations to pump water out of the cave went on despite heavy rain showers on Sunday and Monday.
Narongsak said this phase might take longer than the previous two rescue missions, with the longer first mission taking 11 hours.
The challenging mission involved each of the boys wearing a full dive mask as a diver leads the way carrying their oxygen tank while being guided by a rope.
The tech entrepreneur tweeted Tuesday morning he'd "Just returned from Cave 3" referring to the rescuers' command centre inside the extensive cave network.
