The trip down memory first started when Lewis, 30, shared a photo of himself posing in front of the Hogwarts castle at Universal Orlando Resort in Florida on Instagram Monday.
The picture shows the actor, who played Neville Longbottom in the film franchise, grinning as grey clouds surrounds the fictitious school of witchcraft and wizardry.
“There’s a storm coming, Harry,” he captioned the shot.
As captured by the Comments by Celebs Instagram account, Felton, 32, soon left a cheeky comment under the snap. “I used to bully him,” he jokingly wrote.
