It's confirmed that Event Horizon and Resident Evil series director Paul Anderson will be the director of Hunter X Online GAME. According to Deadline, Anderson has given Deadline his concept for the movie version. There's no information on the story or actors/actresses, but the movie could be shot in US or South Africa.

Back in 2012, Anderson revealed his interest in bringing the Hunter X Hunter game series Hunter X Online to the big screen, but since then no news has come through on his involvement. The role-playing video game Hunter X Online is a bestseller for Unigame and should be catnip for tentpole IP-hungry studios. The game is especially popular in Japan and in US.
A new boss Floating Dragon, Yama Tsukami, is landing in the English version of Hunter X Online. It’s an unusual Elder Dragon with an octopus-like body, covered in moss, algae, and other plant life, having the ability to produce gas within its body in order to keep itself afloat.
Known as a dangerous creature, Yama Tsukami could be docile after feeding. But Yama Tsukami will become very hostile if it is surrounded or cornered, swinging its legs slapping on the ground in a frenzy, releasing the bugs from its body to attack enemies and more. Yama Tsukami has a symbiotic relationship with Great Thunderbugs, which allows them to rest inside its body until they mature. In return, the Great Thunderbugs assist the monster by attacking threats. These Thunderbugs can explode when they are near an opponent, causing considerable damage to their target.
