Darlene was played by actress Terry Farrell. She found the character's line about an alien having a "worm in her belly" funny. Regarding the role in general, Farrell commented, "I didn't have very much to say. I got this tape on the New York accent. Then I looked at my lines, and I only have like six lines in the whole script. So that took a lot of the stress off." (Cinefantastique, Vol. 30, No. 9/10, p. 49)
The authors of the Star Trek Encyclopedia (4th ed., vol. 1, p. 448) thought Darlene Kursky "might have existed in some alternate reality, or perhaps only in certain reaches of Ben Sisko's mind."
