Judy Blume is most at home surrounded by books. That’s the predominant impression of a new documentary on the author’s life directed by Davina Pardo and Leah Wolchok, Judy Blume Forever, which premiered at Sundance last month and will begin streaming globally on Prime Video in April.

The film relies heavily on interviews with Blume herself, a wonderfully charming presence throughout the documentary. (“I could be fearless in my writing the way I couldn’t in my life,” Blume explains in the film, referring to the complexities of her own personal life, where she chafed against the confines of her early marriages.) But one of its best components is its emphasis on the readers and how they were and still are affected by her novels.
