1970s was a dark period in my life, was taking drugs: Al Pacino

On being asked if doing series 'Hunters' took him back to 1970s, Hollywood actor Al Pacino said, "Nothing takes me back to...'70s. I just can't go back there." "There's something dark about where I was at, at that time. I was a little bit more, I think getting, you know, taking drugs and drinking and all that in...1970s," he added.
