This press photo, from my collection, has a printed caption attached to the back that reads:
Following a private showing of The Great Dictator, Charlie Chaplin entertained a party of friends at Ciro's. Charlie and Tim Durant stagged it, even though Gene Tierney and Pat Morison were also unattached. Paulette Goddard was on the high seas, headed for New York [for the premiere of The Great Dictator] via the Panama Canal.
