If you want to go for that shallow depth of field, you have to open up the iris on the camera. In a stills camera this may easily result in over exposure. Most photographers would be tempted to start changing the ISO setting or shutter speed. Shutter should be kept at twice the frame rate you are shooting (e.g. 30p –> shutter at 1/60th, 24/25p –> shutter at 1/50th as 1/48th is not supported) to adhere to the 180 degree shutter rule in cinema. A better way to reduce the incoming light: enter the Neutral Density filters from Singh-Ray (effectively two circular polarNew Postization filters combined into one). This gradually reduces incoming light from 2 to a full 8 stops.
