Witness for the Prosecution wow absolutely great, I have the billy wilder collection and this was the first movie I watched, because I'm a fan of Dietrich and I must say she'really steals the show, her performance as an criminal wives, who lies for him, especially when she's in disguise to tell a lie about her self, when I saw her I thought, that's Dietrich, but I thought no It couldn't be and yes she was it really a great performance, maybe her best, it was said that I already knew the end because it was in one of Dietrich's biographies but still you think what would happen, really a great performance, but not only Dietrich also Charles Laughton and Elsa Lanchster are great and funny as well, this is one of the best movies in the Billy Wilder collection.
