Like most of the major Harry Potter kids, Matthew Lewis first appeared as Neville Longbottom in 2001’s Harry Potter and the Sorcerer’s Stone.
So Matthew Lewis’ prominence in the movies increased as the years passed, but that also meant his enthusiasm for the Harry Potter world decreased as they became more work-heavy.
Seeing this play, along with years having passed since the movie series concluded, has made him a Harry Potter fan once again.
Neville started out as s shy and bumbling student with a knack for Herbology, but as the books/movies progressed, he gained more confidence.
