This was when Pacino (and De Niro,of course) never mind Bill"tThe Exorcist (1973)" Friedkin could seemingly do no wrong...Just imagine how "controversial" this was back in 1980!..the "deep cover" that the character embarks upon breaches a lot of taboo areas,and just think of how ,rightly or wrongly, the stigma of HIV hung over things...One abiding memory is how we joked about being careful NOT to let ANYTHING hang out of your back pockets.
