Girls creator Lena Dunham and The Breakfast Club star Molly Ringwald are among several public figures who come out in praise of Judy Blume in the trailer for Judy Blume Forever, a wonderful new documentary about the children’s literary icon.

“Everything I learned about sex or crushes, I learned from Judy,” Ringwald says in the trailer.

“She allowed young women to be as complicated and messy and funny as we are,” says Dunham.

“My daughter said, mother, couldn’t you write a book about teenagers who fall in love and do it, and nobody has to die?” Blume says of her famous book Forever… in the trailer. “I grew up as a good girl with a bad girl lurking inside. So by the time I started to write, I really had lot to get out. I could be fearless in my writing in a way that maybe I wasn’t always in my life.

Judy Blume Forever arrives on Amazon Prime Video on April 21.
