Large parts of the film depict events that never happened; in particular the sequence where Bronson is released 'for being sane' during the 80's (Charlie was declared sane, sent back to prison and subsequently released in 1987), goes to live in a brothel (the 'brothel' is supposed to depict Uncle Jack's flat), starts a bare-knuckle boxing career (Charlie did box but never bare fisted) and gets his 'new' name, (His boxing promoter changed his name but not officially) then proposes to a girl before being sent back to prison.
