Hollywood beauty Charlize Theron raised eyebrows when she challenged a group of hardened miners to play darts with her - and won.

Theron was spending time in a Minnesota mining town to research her character in upcoming movie North Country, and decided to impress the locals with her dart-throwing prowess - which won her stacks of cash in bars throughout the area.

She quips, "I just needed some extra cash to chip in towards the film's budget."
