Harry Potter script sells two million copies in two days
The script for London stage production Harry Potter And The Cursed Child Parts One And Two has sold more than two million print copies in North America in its first two days of publication, Scholastic said.
It is among the fastest-selling works in history and a remarkable number for the script to a play.
But it is well below the 8.3 million copies sold in 2007 for the first day of Harry Potter And The Deathly Hallows, JK Rowling's then-presumed finale for her fantasy series.
A text edition of hit musical Hamilton has also been a best-seller this year.
Reviews for the Cursed Child book have been mixed, but the new Potter has topped the best-seller lists of Amazon.com and Barnes & Noble.com and brought in readers nationwide over the weekend for midnight parties celebrating the release.
Several previous Rowling books were also high on the Amazon and Barnes & Noble lists in recent days.
Sales for the e-edition for Cursed Child, released through Rowling's Pottermore website, have not been announced.
The script is based on a Rowling story and co-written by Jack Thorne and John Tiffany.
