The continuation of the Star Wars saga in the Disney era went through a lot of changes from concept to screen. JJ Abrams revealed his original storyboards for The Force Awakens, which had a different opening scene. No, it wasn't Luke's hand falling through space, but a more expository look at Jakku.
The Mary Sue explains.
Animator Tim Gray made the above video, based on J.J. Abrams’ own unused storyboards, which mirrors the opening of A New Hope to satisfying effect. The familiar scene has smaller ships being tailed by a looming Star Destroyer, but then it flips the script: They’re actually tugging the decrepit ship along to its final resting place on Jakku, where scavengers like Rey will inevitably harvest it for parts.They did the right thing in going with a real battle to open the film. As the prequels taught us, action always trumps explanation.
