In a post on social media, Alton Towers said:
"We are sorry to say that we've taken the very difficult decision to postpone the opening of Gangsta Granny: The Ride until Spring 2021. We are hugely disappointed, as we know many of you will be. So much hard work has gone into the design and build of what promises to be a brilliant, unique ride experience. We look forward to launching Gangsta Granny: The Ride, and the other attractions in the brand-new area inspired by The World of David Walliams next year with all the fanfare they deserve. Thank you for your understanding."
Published by HarperCollins Children’s Books, Gangsta Granny tells the fun story of Ben who discovers that his Granny is secretly an international jewel thief.
The thrilling new 4D ride experience will see guests join the main characters as they attempt the greatest heist in the history of the world: to steal the Crown Jewels.

On-board a Royal Carriage, guests will set off on a Crown Jewels tour only to be caught up in Ben and Granny’s audacious adventure. The ride will whizz, twist and spin passengers 360° through a series of scenes where they will see, feel, hear and even smell an electrifying and unique re-telling of the Gangsta Granny story.
Using state-of-the-art special effects, 3D projection-mapping and animation inspired by the artwork of Tony Ross, guests will descend with Ben and Granny into the sewers, be chased through the streets of London and come face to face with the Queen: but will the madcap scheme succeed?
