Going off on a tangent, slightly - "The Band Wagon" is on now on on TCM - when Tony Hunter arrived on the 20th Century Limited at Grand Central, he was talking with a porter. For some reason, this time I notice that the porter's voice is familiar. Sure enough, the actor was a porter six years later on the 20th Century Limited in "North by Northwest." Think "A message from the lady in car 3901."
The actor, Ernest Anderson, was also a club car steward in "The Palm Beach Story," a porter in "Lady on a Train," a dining car waiter in "Without Reservations," and a red cap at Albuquerque in an episode of "Cannon." Among his many other roles.
