Need help finding a suitable movie quote

After poring over this problem for days, I finally decided to ask you guys for help.
My novel has been finished for quite some time, and I've mailed the outline to publishing companies, without success, but now I want to enter the full manuscript in a competiton. Each chapter opens with a more or less famous movie quote that fits the events that follow. Only one pivotal chapter towards the end has no quote yet, and somehow I can't find one... Maybe you guys can help?

Movie should be well-known, should be PG13-ish or under, ideally a movie that a 12-y-o boy may have seen.
Situation: one boy helps another boy climb out of a celler where he's been locked up, while the house is on fire...
Whole novel is about friendship and courage. Possible themes: climbing, fire, buddy moment....

It would even help if you don't know an exact quote but remember a scene that fits, in that case I can go to imdb and hunt for a suitable quote.

Your help would be greatly appreciated. :)
