Some crime noir in San Francisco.

Is that Bullit?

French Connection?

A Sherlock Holmes movie. Sherlock Holmes And The Case Of The *mumble mumble*

Nope. Here's one that should be a dead giveaway.

The Verdict

That is correct. Great film, it's the only court-room drama I personally like, and I like it a lot.

How about My Cousin Vinny - Now there is some court room drama ;-)

Here's one

Purgatory
If I am right someone else is free to take my turn as it will be tomorrow before I could post another movie.
