One of the reasons The Honeymooners felt so real to audiences was the fiery personality of Ralph Kramden.
His shouting matches with Alice became some of the most famous scenes in television history.
But according to stories from the set, part of that intensity came from the acting style of Jackie Gleason himself.
Gleason disliked rehearsing scripts in detail. Instead, he preferred to perform scenes using only a basic outline of what would happen.
This meant his co-stars sometimes had no idea exactly what he would say next.
For actors like Audrey Meadows and Art Carney, this could be both exciting and terrifying.
They had to react instantly while cameras were rolling.
But that unpredictable energy also helped create the spontaneous comedy that made the show legendary.
