Bronson reminds me of all the old explorers like Scott and livingstone. Clear off for decades/forever somewhere dangerous but express passionate love and affection from afar. According to how some tool of a historian interpretes some old yellowing postcard they may have sent.
More an anecdote but i knew someone who ended up in the same prison for shooting someone, as he was a good artist Bronson would ask him to draw/paint pictures for him and in return made sure he was ok in prison, was a long time ago.
