She provided additional story material for Mulan, released in 1998, and co-wrote the book of the Disney musical Aida, which opened on Broadway on 2000 for critical acclaim. In 2007, she completed a screenplay where an older Alice, from Lewis Carroll's Alice's Adventures in Wonderland, goes back to Wonderland, from an idea she had in her head for many years. She presented this screenplay to producers Suzanne Todd, Jennifer Todd, and Joe Roth, who took it to Disney. The studio immediately accepted the project, attaching Tim Burton to direct. Alice in Wonderland, released in 2010, was a huge box office success, earning more than $1 billion, and making Woolverton the first and only female Screenwriter with a sole writing credit on a billion-dollar film.
