Amazon Prime Video dropped a trailer for Judy Blume Forever, the upcoming documentary about the legendary author of books for young readers.

The trailer opens with Blume saying, “My daughter said, ‘Mother, couldn’t you write a book about teenagers who fall in love and do it, and nobody has to die?’ And I thought, ‘Yes!’”

Several celebrities are shown paying tribute to Blume, whose novels, including Are You There God? It's Me, Margaret., Forever…, and Tiger Eyes, are widely considered classics.

“Everything I learned about sex or crushes, I learned from Judy,” says actor and author Molly Ringwald. Girls creator Lena Dunham explains, “She allowed young women to be as complicated and messy and funny as we are.”

And author Jason Reynolds says, “I don’t think Judy Blume wrote her books to be timeless. I think she wrote her books to be timely. And they were so timely that they became timeless.”

Another clip shows Blume explain, “I grew up as a good girl with a bad girl lurking inside. So by the time I started to write, I really had a 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 is produced by Imagine Documentaries and directed by Davina Pardo and Leah Wolchok. It’s scheduled to premiere on April 21.
