They did the right thing reshooting the movie to remove Spacey.
I can't watch a Robin Williams movie now, just looking at a movie cover with his face is depressing I just think of his fragmented dimentia ridden mind commiting suicide on his knees by doorknob asphyxiation. The only movie of his I could watch so far is What Dreams May Come and now this line in the movie sticks with me "suicides don't go to heaven..."
