Today, a video has surfaced on YouTube of what appears to be set footage from The Force Awakens.

SPOILER ALERT! DO NOT CONTINUE IF YOU DO NOT SEEK ANY SPOILERS!

So here is the footage:

UPDATE:

Unfortunately, it is being blocked from all sites, except for one, the good folks at MakingStarWars have a working link up:

This footage appears to be the escape from Jakku scene depicted here:

In the footage you can hear Rey say “Let go of me!” and Finn replies with “We gotta move!”. It seems as if they have been caught by surprise. It is safe to assume that this is an early point in the movie.
