In a 2017 interview, The Wrath of Khan director Nicholas Meyer stated about Coulson, "My memories [of her] are extremely pleasant. She was a lovely woman and she [was] very good at her job. She was very much a team player and very encouraging to me [....] She was not a judger and she was quite tireless [....] She never lost her extremely good humor or her professionalism. I liked being around her very much and it is a real loss."
