Okay, I don’t know much at all about this movie. I remember it playing on the sci-fi channel network around the same time The Langoliers movie came on tv. It was like a group of people trapped in this huge room, every thing was white, it may have been like a foam or stryofoam type texture. And they were trying to find their way out. It is not either version of the cube.
sounds like “Five Characters in Search of an Exit”

classic Twilight Zone episode.
Hmm I don’t think that is it. It was in color, and it might be a full length movie
