The backdrop behind the characters is one I’ve used in multiple settings. It was originally constructed for the “hallway” scenes, but I’ve decided it’s useful as a generic backdrop for scenes that take place in the S-Team’s headquarters. I use the “angled” doors to delineate sequences that take place there as opposed to someplace else. The Conference Room and Monitor Room sets also have these doors.
Obviously, the architect for the Fabulous S-Building watched too much Star Trek as a kid.
