What movie endings would be ruined if the camera kept filming for an extra twenty seconds?

Truman Show: What is he going to do after exiting the studio? Meet and greet with his fans?

Memento: It's like restarting the movie.

8 Mile: He'll just keep on walking.

The Italian job (original version): Seeing the bus hanging there and Michael Cain piping up with his optimistic scheming was perfect.

Die Hard: We pan upward and see a giant lasagna stain on the ground where puking firemen are scraping Hans Gruber and his suit off the pavement

Avatar: twenty seconds after they're off planet, you know that corporation is ordering an orbital nuke on the planet.

Pulp Fiction: I really would love to know what was in that case.

Star Wars The Force Awakens: I love the stare but if that went on just 20 more seconds you would think Luke had a stroke or they couldn't remember their lines.
