Marlena was very, very good in Witness For the Prosecution.
What a movie that was. But how could it be anything but? Story by Agatha Christie; starring Charles Laughton, Elsa Lanchester, Tyrone Power, Una O'Connor -- and of course Marlena in the title role -- it would have taken a lot of effort to make it anything but great.
And great it was.
And I want to watch it now.
