Just stopped by IMDB to be greeted by the news that Robert Wise, one of the directors of the West Side Story movie, has passed away of heart failure. He also directed The Sound of Music movie.
For a little while, more info can be found here on IMDB. They may be changing the link though if more breaking news comes through. (Never mind, IMDB took down the nice obituary already.) Robert Wise's info page can also be found there.
