The episode premiered on BBC One on November 26.

Oxalis took charge of all the necessary preparations to facilitate the smooth filming process for the BBC crew.

A touch of nostalgia accompanied Chau A as he watched the splendid visuals of Son Doong and Va Caves featured in Planet Earth for the first time after the episode aired on BBC One.

Chau A stated that previous filming teams had used low-resolution cameras or drones to capture the landscapes, failing to do justice to the alluring beauty of these caves.

The Planet Earth film crew, however, utilized two drones equipped with advanced lighting and recording equipment to capture the stunning and captivating landscapes that had previously eluded other teams, according to Chau A.

The BBC crew consisted of six members, led by producer Theo Webb.

They toiled away diligently from January 27 to February 19 last year, spending a consecutive 18 days filming scenes in pitch darkness.

This episode, shot within the caves, demanded a massive investment, surpassing the budget of American morning television program Good Morning America or Alan Walker’s music video Alone Pt.III, both also filmed in the caves.

Chau A revealed that the BBC crew brought over one metric ton of equipment and machinery to film Vietnam’s natural beauty inside these caves.

“I hope that this nature documentary will contribute to boosting tourism in Vietnam,” stated the Oxalis representative.

Speaking of Planet Earth III, 97-year-old British broadcaster, biologist, and natural historian David Attenborough mentioned that in this rapidly-changing world, “they represent the greatest natural wonders of the earth, wonders that may never be seen again.”

Attenborough also unveiled extraordinary footage capturing the intense battles for survival between wild animals featured in this hit documentary.

He further added that Son Doong Cave, the deepest part of which is among the world’s greatest natural wonders, is home to white blind fish that can be found alive in some of its pools.

Upon entering Son Doong Cave, associate producer Georgina exclaimed, “It’s unbelievably dark in here!”

“We were aware that we were standing near a river and had to cross the first river to venture further into the cave. Once we illuminated it, we were truly taken aback by its vastness,” he recalled.

“The sheer immensity of the cave was unimaginable; it was undoubtedly a challenge to film,” added Theo Webb.
