Irish James Bond star Pierce Brosnan has been charged with stepping out of bounds in a thermal area during a recent trip to Yellowstone National Park in the US.

The Irish actor walked in an off-limits area at Mammoth Terraces, in the northern part of Yellowstone near the Wyoming-Montana border, on November 1, according to two federal citations issued on Tuesday.
