My 20th Century, a new Hungarian film written and directed by Ildiko Enyedi, is a number of wondrous things. It's a bracing combination of wit, invention, common sense and lunacy. It's a gravely comic meditation on civilization at the turn of this century. It's also about light and shadow and electricity, Thomas Alva Edison, movies and what it's like to be Hungarian in a world where no one is quite sure where Hungary is.
