Auntie Mame's staircase
You know the one. It kept getting re-decorated for each new chapter of the film. It was a "standing set" at Warner Brothers back in the 1950s used in almost a dozen films. I've collected some of them and put them on YouTube. It's interesting to see how different paint, lighting and bannisters can change it. Check it out.
