However, in the case of movies, the artwork is (usually) moving. Even though the frame has to move, still it's there.
This can definitely be a good thing when you're actually making a movie. Sometimes, your filming location may not be perfect. And while it may not be ideal, with a little creative framing, you can make it work.
On one of our film shoots, our location was a church with a lot of stained glass windows. During pre-production, we noticed that one of the windows had been boarded up. As it turned out, the church was doing some renovation work on the old windows.
No problem. But since we didn't need the "boarded-up-window look" for this scene, we had to figure out angles that avoided showing that particular window.
The crazy thing was that when we went back to film there a week or so later, the original boarded-up window had been fixed. But the window next to it was now boarded up!
Adjustments had to be made for some slightly different camera positions to avoid filming the new boarded-up window. (At that point, we did ask if they would halt the window-beautification project for the duration of our filming. They did.)
Frankly, it doesn't really matter what's outside of the frame of the camera. Nobody will ever see that. That's the magic of filmmaking. You create a reality out what makes it into frame...
Sometimes, it just might take a little creativity.
