Word Wars is one interesting trip down obsessed lane. The film's subtitle: Tiles and Tribulations on the SCRABBLE Circuit.
The film highlights four top SCRABBLE players who regularly, and frequently, compete in tournaments. So much so that three of the four don't have jobs. They practice, practice, practice and compete. SCRABBLE is their life. For example, at tournaments after the competition is finished for the day, they play SCRABBLE.
One of the best moments in the documentary takes place at a tournament. It's at a large hotel. After a round several players take a SCRABBLE board out to the hall, sit on the floor and deconstruct the last round. Down the hall there is a bride, in full bridal gear, looking at them with a look of confusion and horror.
