At the 2017 D23 Expo, Disney officially confirmed that a Ratatouille Attraction will be added to Epcot's France Pavilion. The attraction will be identical to Ratatouille: The Adventure from Disneyland Paris and will be placed between the existing Morocco and France Pavilion. The new attraction is not expected to result in the closure of any existing attractions or facilities currently in the France Pavilion.
While no specific date has been given, the attraction is expected to be open by 2021.
