"Sunset Blvd." CAST OF CHARACTERS —— Themselves - You used to be in silent pictures. You used to be big! - I am big. It's the pictures that got small. - I knew there was something wrong with them. - They're dead. They're finished. There was a time in this business when they had the eyes of the whole wide world. But that wasn't good enough for them. Oh, no! They had to have the ears of the world, too. So they opened their big mouths and out came talk, talk, talk. - That's where the popcorn business comes in. You buy yourself a bag and plug up your ears. The address is 10,086 Sunset Boulevard. There's nothing tragic about being 50, not unless you try to be 25.
