Familiar staircase in 'Tea for Two' also later used by 'Auntie Mame'
The staircase where Gene Nelson did his spectacular dance routine has been used in at least 14 other Warner Brothers films. I've put together clips from most of them and it's fun to watch the magic Hollywood does in set design as it changes the look of this standing set used from the 40s to the 60s.
