The big thing to take away from the final trailer for Kong: Skull Island is that it's... big. Very, very big.
So big in fact, that Kong's able to hurl trees and helicopters are other helicopters. That kinda big. While this trailer does appear to be leaning less heavily on the Vietnam War-era music, the visuals and costumes definitely are from that era - not to mention all the Hueys flying around Kong.
Take a look.
