Actor Daniel Radcliffe mourned the demise of Dame Maggie Smith, who played the role of Professor Minerva McGonagall in 'Harry Potter' movies. "The first thing I asked her...was 'Would you like me to call you Dame?' She laughed and said something [like] 'Don’t be ridiculous!'" "The word legend is overused...but if it applies to anyone...then it's her," he added.
