The 25-year-old actress took to Twitter to voice her support to the casting of black Hermione, which received a lot of flak from fans on internet, reported People magazine.
“Can’t wait to see Noma Dumezweni as Hermione on stage this year,” Watson wrote adding a string of heart emojis.
In the past author JK Rowling also tweeted her support for the casting decision.
The two-part play, which is based on a new original story by Rowling, catches up with Harry, Ron and Hermione as adults before shifting the focus to Harry’s youngest son Albus.
