According to an uncredited actor, the script remained unchanged between the two periods of filming.
However, unlike the reshoots on 2016’s Rogue One: A Star Wars Story that involved an uncredited Tony Gilroy writing new dialogue and directing entirely new sequences (including the climactic battle), the additional photography on Solo is said to consist of scene-for-scene do-overs of things previously shot. “It’s exactly the same script. They’re filming exactly the same things. There’s nothing new,” says the actor, adding: “[Lord and Miller] used whole sets. But Ron is just using parts from those sets. I guess they’re not shooting wide angle. Maybe to save money.”
