City of Angels (1998)

Continuity mistake: At the end of the film before Nicolas Cage jumps in the ocean, the sky is overcast. Once he is in the ocean, the sky is clear blue.

Continuity mistake: In the scene when Meg Ryan gets into bed she has on a broad strapped tank top. She's tossing and turning in bed at 3:14am, then picks up a book and is suddenly wearing a differently strapped top.

Revealing mistake: In the scene by the mirror, Cage has been removed from the mirror. Just seconds before, when we are moving from the back of Meg Ryan's head to Nic Cage's face, you can see his nose and face in the corner of the mirror.

Maggie Rice: We fight for people's lives in here, right?
Jordan Ferris: Uh-huh.
Maggie Rice: Don't you ever wonder who it is we're fighting with?

Maggie Rice: I'm not afraid. When they ask me what I liked the best, I'll tell them, it was you.

Maggie Rice: Got a message for me?
Seth: I already gave it to you.
Maggie Rice: Well, did you use my pager? 'Cause I usually don't get my messages unless you beep me.
Seth: You've definitely been beeped.
