Sunset Boulevard ★★★★

With its opening images of a doomed narrator, this film will have its hooks in you. As they follow their desires to obtain or recapture romance and fame, you'll be allured and repulsed by the two leads. And by the climax you will be spellbound by Gloria Swanson's wide-eyed, half-smiling, half-clenched teeth. Plenty of Old Hollywood cameos and one of the best endings in cinema history.
