At Disney's D23 Expo on July 15th2017, a presentation uncovered additional details about the attraction's story. Artwork depicted Chewbacca and Hondo Ohnaka outside of the Millennium Falcon and it was revealed that an agreement between the two will lead to a crew being needed for an as yet unknown endeavor. On December 13th, 2017, the Disney Parks Twitter feed posted an image from the interior of a portion of the ride.
On March 28, 2018, it was revealed that Instead of a traditional ride film, the Millennium Falcon ride film is being developed by ILM Experience Lab as a real-time rendered experience in partnership with NVIDIA and Epic Games. The "ride film" will run on the Unreal Engine and be powered by a group of eight NVIDIA Quadro P6000 GPUs, with five QuadroSync projectors offering ultra-high resolution picture.
The attraction will put multiple guests into the cockpit of the Millennium Falcon, where they will each have a specific job during a mission. The outcome of the ride's events and the performance of the guest will give them a reputation that will affect other experiences within Galaxy's Edge beyond the ride itself. The official name of the ride has yet to be revealed, though internally, it has been given the working title "Big Bird".
Originally, guests were to have completel control over the Falcon's path. Disney later changed this over fears that certain guests would intentionally crash it in seconds to ruin the experience for other guests for their own pleasure.
