Parece ser uma combinação de criações reais, simuladas (parciais) e CGI, como seria de esperar
In a scene near the start of Kong: Skull Island, a band of adventurers buzzing around in military helicopters comes face-to-face with the monster that gives the film its title.
A spectacular vertigo-inducing battle ensues between Kong and the copters.
Much of that scene was done at Industrial Light & Magic (ILM) Singapore. Visual effects supervisor Jeff Capogreco, 41, says the scene "introduces us to Kong and he isn't very happy. People are invading his home".
Real actors inside dummy aircraft whirl around digitally created Kong, with the fight taking place against jungle scenery and sky which might also be painted in by computer.
"Singapore did the helicopters being smashed and crushed. Kong is roaring and jumping," says Mr Capogreco, who has worked here since 2014.
Para colisões no chão, parece que o par de manequins de helicóptero foi usado ... como pode ser visto aqui (c.50s)
Helicópteros são caros , muito mais caros do que ter uma equipe de VFX juntos (especialmente porque são itens comuns em filmes e seriam muito "prontos") e usando vários duplicados CGI .
