Finn and Rey's relationship drives a big chunk of the action in The Force Awakens, but if it wasn't for Harrison Ford's on-set injury that relationship might be much different.
Early on in filming, Ford's ankle was shattered by the door of the Millennium Falcon in a fluke accident. It forced filming to delay, which gave JJ Abrams time to think about what he'd shot so far, and retool pieces of the script.
“When I was on the set of the Millennium Falcon and we started to do work with Rey and Finn, the first time we did it, it didn’t work at all,” Abrams revealed while speaking at the Tribeca Film Festival. “It was much more contentious. I didn’t direct it right. It was set up all wrong, and when Harrison Ford got injured — which was a very scary day — we ended up having a few weeks off, and it was during that time that I really got to look at what we had done and rewrite quite a bit of that relationship. So when we came back to work again, we actually just reshot from the ground up, those scenes. It was an amazingly helpful thing to get these two characters to where they needed to be.”
All that work helped create a friendlier tone between the two characters, getting audiences to root for both of them, and setting up amazing moments like this:
