ABC is getting “girl power.”

The network is developing a two-hour telefilm based on psychologist Dr. Mary Pipher’s nonfiction bestseller “Reviving Ophelia: Saving the Selves of Adolescent Girls.”

In “Ophelia,” first published in 1994, Pipher cites case histories to illustrate the struggles adolescent girls endure in the quest to define themselves. Robert Greenwald brought the book to ABC, where it is being developed for Greenwald to produce. Greenwald estimates the telefilm’s budget will fall into the $3.5-4 million range.

Former Walt Disney Pictures creative executive Heidi Frey will write the script for the project, which Greenwald describes as a “coming-of-age drama with a sense of humor.” The telefilm will center around a group of teenage girls who go on an outdoor adventure course where they deal with issues such as friendship, body image, and sex.

Robert Greenwald Prods. is in post-production on “The Audrey Hepburn Story,” starring Jennifer Love Hewitt, also for ABC. The company is also in post-production on “Steal This Movie,” a feature film about 1960s activist Abbie Hoffman.

ABC executive VP of movies and miniseries Susan Lyne and VP of movies Quinn Taylor are shepherding the project’s development.
