Turner Classic Movies on Instagram: "Lon Chaney's performance in THE PHANTOM OF THE OPERA ('25) was universally praised and so were the elaborate sets and costumes Universal spared no expense in producing the film. They built the first steel and concrete stage in Hollywood which housed the entire interior set of the Opera House, the backstage area, and the grand staircase. (This stage, which still stands today on the Universal lot, is the only surviving set from any Chaney film.)"
