Lord of the Rings: Fellowship of the Ring Extended version - Vanishing Ring
In the scene where Frodo tells Galadriel he would give her the ring if she asks for it, she reaches out with her right hand towards the ring. Her hand is bare. A few minutes later, he tells her he feels so alone, and she says, "To be a ring-bearer is to be alone." And reveals to him her right hand, but this time it has her ring on it!
