Quite a few people in the media and those who were close to Heath believe that it was his over the top performance of The Joker in the new Batman movie that played a part in his death. Heath apparently delved into this psychotic character so deeply that it became very difficult for him to separate pretend from reality – thus the reason he was taking sleeping pills. In this video, Christian Bale takes on this theory; basically, his take is that it’s absolute bollocks.
By the way, what accent is Christian Bale sporting? Seemed to go from Austrailian to Bronx and back again.
