To start, I'll highlight one of my favorite bits of visual foreshadowing, from 1993's Jurassic Park. (dir. Spielberg) In the scene where our main cast is arriving at the island by helicopter, owner John Hammond, (Richard Attenborough) announces that they have to come in fast, and things will get shaky. Everyone immediately buckles their safetybelts without a hitch:
With the exception of Dr. Alan Grant (Sam Neill), who finds himself stuck with two female pieces, unable to connect:
Thinking quickly, Grant does what come instinctively, and just ties the two belts together, fashioning an improvised harness for himself.
Wait a second, here. Two female components that aren't supposed to go together, but they do anyway, to fulfill their natural function? Wait, that seems like it could be important later...
Life Finds A Way.
