Lloyd Dobler from "Say Anything"
John Cusack's boombox scene is likely cinema's most heart-melting moment. When his character Lloyd uses a last-ditch effort to win over the girl he loves, he shows up outside her house with a boombox, professing his love. It's his most noteworthy movie to date.
Princess Leia from "Star Wars: Return of the Jedi"
Carrie Fischer's most iconic moment as Princess Leia was in "Return of the Jedi." She's abducted by Jabba the Hut and is kept as his slave until her crew swoops in to rescue her. This is one of the only times we see Leia not wearing her classic space bun hairdo.
