Production designer Carey Meyer built the ship "Serenity" in two parts. It was built as a complete set. It had ceilings and working lights built in as part of the set that the cameras could use. It also had movable parts. This helped with moving the camera around inside the set. There were other good things about this set design. One was that it let the people watching feel that they were really in a ship. For Whedon, the design of the ship was very important. It defined the known space for the viewer. He wanted to show that it was simple and that it was "beat-up but lived-in and ultimately, it was home". Each room had a feel to it, usually shown by the paint color.
