* During production of ''SuddenlyLastSummer'', the director, Joseph L. Mankiewicz, treated the troubled Montgomery Clift, who was dealing with some pretty bad substance abuse problems during production, very poorly. Most of the other cast and crew members were obviously sympathetic to Clift and pretty disgusted by Mankiewicz's behavior, but few made a display of it like Katharine did. When filming was over, she went up to Mankiewicz, asked if she was no longer needed for filming, and ''spat right in his face''.
