In 1978, the world was a different place.
There was no Google yet. Or Yahoo. Or Twitter, for that matter.
In 1978, the year of your birth, the top selling movie was Grease. People buying the popcorn in the cinema lobby had glazing eyes when looking at the poster.
Remember, that was before there were DVDs. People were indeed watching movies in the cinema, and not downloading them online. Imagine the packed seats, the laughter, the excitement, the novelty. And mostly all of that without 3D computer effects.
Do you know who won the Oscars that year? The academy award for the best movie went to The Deer Hunter. The Oscar for best foreign movie that year went to Get Out Your Handkerchiefs. The top actor was Jon Voight for his role as Luke Martin in Coming Home. The top actress was Jane Fonda for her role as Sally Hyde in Coming Home. The best director? Michael Cimino for The Deer Hunter.
