Throughout the film, Master Chief John James Urgayle, played by Viggo Mortensen, reads and quotes poetry. In real life, Viggo is very fond of poetry; in addition to being an accomplished poet, skilled actor, artist, painter, and horseback rider, he published a book of his own poems entitled 'Ten Last Night' before he became well known.
