"Happiness can be found even in the darkest of times, if one only remembers to turn on the light." is preserved here as a credited line from Albus Dumbledore in Harry Potter and the Prisoner of Azkaban (2004), not as an anonymous standalone saying. The combination of fantasy and adventure storytelling and Michael Gambon's performance is part of what gives the line its staying power, which is why this detail page keeps the movie, character, and actor together in the same context.
