Greg Mills remembers attending Andrew Lloyd Webber’s “The Phantom of the Opera” as a youngster. Little did he imagine that one day he would be Raoul, Vicomte de Chagny, in the production playing in The Kennedy Center Opera House through mid-August.

“Raoul is a fascinating character because of the growth he goes through,” Mills says. “He is charming at first and focused on having fun, but as the story progresses, he becomes more mature and supportive toward Christine.”
