What is the first movie you remember watching in the theater?

I miss the vibe of what was once a REAL occasion - going to the movies. It was something special. It was always crowded, and the theatres were always full. The foyer was full with the hum of excited families and friends all buying snacks and getting tickets.
There were formal ushers for seating, politeness and sociability everywhere.
Now its almost lonely and quiet.
