What is the best movie opening? I'll start with a classic:
Once Upon a Time in the West (1968)
Veeeery slow opening, no words from the main actors, no music, lot's of ambient sounds, wide vista shots, faces like mountain ridges
Opening part I
Opening part II
Opening part III
From the 90s:
Most memorable scene from that movie. Descent into madness and hammering 90s techno rave.
