I watched "witness for the prosecution" out of the blue and was instantly hooked to courtroom dramas. So I tried to dig up the best courtroom drama movies. I consulted a few lists and am I glad I did. I found four movies that are generally accepted by all. Anatomy of a murder was one of them; other three being, witness for the prosecution, to kill a mocking bird and Michael Clayton.
James Stewart has done a great job on the portrayal of the "humble country lawyer". The character become so alive that they make you want to be one of them. George Scott has done a wonderful job as Asst. State Attorney General Claude Dancer. He is bang on the target as the shrewd lawyer who knows how to skirmish around in the courtroom.
If you love to talk, argue and everything; then this genre is for you and the movie is the best start. It makes witness for the prosecution look pale at times with the tension in the environment at times.
