The plot twist at the end of Working Girl (Twentieth Century Fox, 1988) turns on Tess McGill (Melanie Griffith) explaining her stroke of combinatorial creativity in coming up with a business pitch. Because she had juxtaposed several disparate ideas from the New York Post several pages from each other in a creative way, she got the job and Katharine Parker (Sigourney Weaver) is left embarrassed because she can’t explain how she came up with a complicated combination of ideas.
Tess McGill has slips of newspaper with ideas on them and a physical box to put them in.
slips with ideas + box = zettelkasten
Bonus points because she links her ideas, right?!
