OK, I'm looking for this movie for a long time now but I don't remember much of it, I've seen it when I was a kid and it's stuck in my brain ever since. Now, here is what I remember:
A family (I know they were husband and wife, but I'm not sure if they had kids) is transported underground or some kind of other dimension where they were forced to compete in some kind of TV show. I remember that they were sitting in chairs that got higher every time they did something correct and eventually they've gone high enough to get back on surface.
I know it's not much, but that's everything I remember.
