The 007 actor has pleaded not guilty after allegedly entering prohibited areas of Yellowstone National Park. Brosnan faced two charges after he was accused of hiking into a thermal area in November last year. The Mammoth Terraces hot springs and thermal area are both delicate ecosystems within the park. They are also dangerous; 20 people have died previously by falling into boiling water, and last November a deceased man was found floating in one of the hot springs. The court documents labelled the charges against Pierce as a "petty offence"
