Multiple reports say Colin Firth has been announced to star in a biographical film about sex therapist Dr Alex Comfort. The articles also reference remarks attributed to Comfort’s son, who discusses early public reaction to Comfort’s widely known erotic manual, “The Joy of Sex.” In the accounts cited, the son says he felt “embarrassed” when the book first came out, reflecting on the personal and family impact of the manual’s popularity and visibility. The reports note that the son’s comments are drawn from an earlier meeting with journalist Frances Hardy in 2022. The coverage frames the project as a biographical depiction of Comfort, described as an eccentric sex therapist, while using the son’s recollections to add context about how the publication was received in private life. No additional details about production timelines, cast beyond Firth, or specific plot points are included in the provided excerpts. Overall, the sources align on the film announcement and the cited reaction from Comfort’s son regarding the book’s initial release.
