Al di là di ogni ragionevole dubbio

I remember seeing this in 1970 in the theater. I wish it would be released on DVD. What I remember about it was that a doctor was being charged with the murder of his wife. The Lawyer never had anything to do with defending an accused murderer. This was his first such case but no one could have asked for a better defense. He basically created doubt in the jurors minds by demonstrating during the trial that not only did others have a motive for killing the doctor's wife but they could just as well have done it. While the defense presented in the movie may not hold up in a modern setting - in 1970 before DNA evidence was possible this defense was most effective. I remember a bit more but enough said ... Hope this comes out on DVD.
