Anne Rice's Immortal Universe was the culmination of nearly fifty years of bad business deals, scandals, and squandered opportunities. The author desperately wanted to see her work onscreen. On her website, she claimed that her agent was constantly making contacts in Hollywood, hoping to find a deal worth their time. There were some well-known adaptations, as we're all aware, but what we saw was just the tip of the iceberg.
The author imagined lengthy television series, multiple seasons, and theaters packed to the brim with fans. She loved the cinema, and she was always quick to point that out. She was constantly talking about her favorite films--Rebecca and The Red Shoes. She loved the glitz and glam of old Hollywood, and she believed that her work could fit in with those fabled titles. But nobody could agree as to how it should be done, and Hollywood didn't think that fans were ready for homoeroticism and questionable morals.
When she signed away the rights to her work--a little over a year before her death--she must've felt like she had completed her bucket list. We can also safely assume that she was a bit concerned. Creative control was a source of contention for her. Interview with the Vampire was an allegory for the death of her young child. Lestat was her one great love. She spent decades pouring everything she had into those books, only to hand them over to a group of shameless profiteers. It must've been terrifying.
