Lynda Obst, a New York journalist turned Hollywood producer who promoted women in films like “Sleepless in Seattle” and “Contact” while writing incisive dispatches from Tinseltown for outlets like The Atlantic and The New York Times, died on Tuesday at her home in Los Angeles. She was 74.

Her brother Rick Rosen said the cause was chronic obstructive pulmonary disease.

Known for her booming, raspy laugh and her startling candor, Ms. Obst was a colorful character even by the standards of a colorful industry.

Even more unusual for Hollywood, she was at times an outspoken critic of the movie industry, especially its treatment of women.

As a producer, she excelled at both frothy romantic comedies and serious science fiction dramas. She helped shepherd Nora Ephron’s seminal “Sleepless in Seattle” as an executive producer in 1993 and the box-office hit “How to Lose a Guy in 10 Days” as a producer in 2003. But she also produced Robert Zemeckis’s “Contact” in 1997 and Christopher Nolan’s “Interstellar” in 2014.

She was an advocate for stories focused on women, and often made by women, at a time when there weren’t many. She pushed, for example, for Jodie Foster to star as an astronomer in “Contact” when it was unusual for a major science fiction movie to have a female lead. An acolyte and admirer of Ms. Ephron, she produced her directorial debut, “This Is My Life” (1992).
