The auditorium of the Vieng Samay has been demolished, leaving only a weedy lot in its wake. But for whatever reason the facade of the theater was spared. From a preservationist standpoint, this is a partial victory. If there is no chance of rehabilitating the theater to its original condition and the costs of maintaining the majority of the structure, even if it's used for other purposes, are not feasible, then at the very least preserving the facade - it's most recognizable feature - is a good thing. With any luck the facade's value will be realized some day and it will be professionally restored. Personally, I think it's one of the more unique theater facades I've seen in this part of the world, if not anywhere.
The remains of the Vieng Samay Theater are literally around the corner from the Bua Savan and there is a hotel directly to the right of it which apparently also used to be a theater. That's at least 3 movie theaters in a relatively small area. Aside from those rudimentary bits of data, I wasn't able to learn much about the Vieng Samay Theater, but it was obviously once a luxurious place to watch a movie.
