Smith reportedly discovered respected actors Kathy Bates and Brian Dennehy, and when the latter wished to perform the play Death of a Salesman in Chicago, Smith made it happen with "superhuman strength and negotiating prowess".
When Dennehy received career-best reviews and a Tony Award, Cummings says the office was relieved, as it may soothe Smith's temper.
But it was not to be: "Brian forgot to thank her," Cummings says.
Cummings, now promoted from her assistant to an agent, says work was a scene of "despair".
Then, her new assistant propositioned a solution that Dennehy had offered: taking out a full-page ad in Variety and Hollywood Reporter.
All they needed was a photo of Smith. Cummings says she thought she had a solution: A picture she kept on her side-table in her office.
The next day, Cummings thought she might have won over, until Smith arrived at work with some horrible news.
