The buildings in the TK theater are actual scale model building fronts with working lights. A good set designer or model builder might be able to recreate this, though it will be expensive. You could also go with a background mural, which you can get printed to cover an entire wall and paste on. You can get painted or photographic style wall murals, though the photographic ones tend to look best to me as they give you a bit more of a lifelike 3d feeling and make the room feel bigger. If you are talking about covering a 20x8 foot wall, it will run you anywhere from $100 and up to cover each wall depending on what mural printing company you use. Here is one inexpensive site: Mural site
Here's some examples
You can use a photograph of your own and have them custom print your own mural (a little more expensive), or use a standard mural image from their library. You could even go to a drive-in, diner or classic car show to really get the background you are looking for. I would recommend a nighttime or dusk scene.
Here is a couple of examples of what I mean, taken from another mural site.
This one is actually a painting
You could also do a fiberoptic star ceiling to make it really lifelike.
You could play around with the size/layout of the image and get really creative and incorporate room treatments into it, or on the bottom half, etc. Some mural companies (like this one, another mural site
) can also print your image on your own custom genuine wallpaper, or on Celtic Cloth fabric for a little more $.
