Several really.
One that comes to mind is the one in Lawrence of Arabia where a man gets left behind as they trek through the scorching desert. The others want to abandon him, but our hero goes back alone to search for him.
Time passes, a young lad is keeping watch, everyone else has given them up for dead, and suddenly Lawrence appears with the half-dead missing man on the back of his camel. They all rush round to help, typical, when it’s all over.
I’m sure at this point there is swelling music, and Lawrence says “Nothing is written”, as earlier he was told that things like this were written and would happen.
Sounds daft, but it chokes me up.
