 Hilary Swank (qv) contracted a bacterial infection from a blister  she developed on her foot during training for her role. The  infection was so serious that she almost had to be hospitalized for  three weeks. Catching the infection in the nick of time, she instead  chose to take a week off for medicated rest and didnt tell  Clint Eastwood (qv) or the producers of the film about the injury,  because she didnt believe it was in character.
