I plan to use Gatorboard for the backdrop and fascia. It is strong, lightweight (the layout is heavy enough as it is!) and resists warping better than masonite. It is also available in a 10' length, so there would be no seam in the backdrop or fascia. It is rather expensive, but I think the trade off will be more beneficial than going with a lesser material.
While I wait for the Gatorboard to arrive, I will investigate lighting options and maybe even build the two hidden staging cassettes.
I'm looking forward to recreating scenes such as below with a backdrop behind it!
