Black boxes
The new owners wanted to give the cinema a sleek, modern interior when they first opened, but there wasn’t enough budget for that until 1933. Once they renovated, that modern design made them one of the forerunners of what came to be called the ‘black boxes’. (In this case, that name would be a bit of a misnomer, however, as the walls were actually painted white so that film could be projected on them.)
These cinemas expressly tried to eliminate the environment as a factor. When the Uitkijk put new chairs in, these were a bit spartan, but that fit in with the idea that the true film lover didn’t care about comfort.
