The play and the movie attempts to cast William Jennings Bryan, perhaps one of the countrys best lawyers and politicians
Well he practised very little so yes one of the best lawyers.
Politician: One term in Congress?
No Bryan was basically a writer and publisher of a liberal newspaper.
And he wasn't a bad lawyer either, he had about ten years of practice under his belt before he ran for congress. Very few lawyers are courthouse rats . . . Darrow however was definitely one, although as a person he was pretty reprehensible.
