Force for Change is a charity beneficiary that asks fans to donate money for various good causes. Often, there are prizes that comes with donating. In 2017, while Solo: A Star Wars Story was still in production, fans had a chance to donate and win the ability to appear in the film. However, this was before the whole director change debacle. I was wondering if a winner was announced and if that winner actually appeared in the film, given the fact that seemingly 90% of the film was reshot.
The winner was revealed as Jeremy R of Annapolis, Maryland.
I've seen no evidence that his walk-on part was/wasn't cut from the completed film but for the record, the prize didn't include a guarantee that the winner would get to walk-on, merely that they would receive a VIP set-tour and a chance to meet the director as well as the possibility of an on-screen background role.
"one VIP tour of the Set Location; double occupancy hotel accommodations at a hotel selected by Sponsor in its sole discretion close to the Set Location for two consecutive nights; transfers to/from hotel and airport; meet and greet with the directors of the Movie; the opportunity for the Winner to be filmed (non-speaking) in a scene for the Movie; and a chance for the Footage to appear in the Movie. Sponsor and Prize Providers do not guarantee that the Footage will be included in the final version of the Movie."
This presumably means that if your tour happened to be on a day when they were filming shots inside the Falcon with just the principal cast, there wouldn't be any walk-on parts that you could take.
