With all the controversy still surrounding CBS' forthcoming Sherlock Holmes adaptation 'Elementary' (as 'Sherlock's Benedict Cumberbatch still talks about it), it's easy to forget that the series itself will prove pretty interesting.  We saw the pilot episode at Comic-Con 2012 and have to say, 'Elementary' is definitely worthy of a little buzz.  But while we wait for announcements of Holmes' classic literary characters gracing the series, what 'Newsroom' star is coming to his aide?

TVLine has revealed that 'The Newsroom' player and rising star David Harbour will join CBS' upcoming Sherlock Holmes procedural 'Elementary,' guesting in at least one episode.  The onetime 'Quantum of Solace' star will take the role of Dr. Mason Baldwin, a brilliant surgeon who aids Sherlock (Jonny Lee Miller) when the iconic detective investigates a murder in a hospital.

Personally, we think he'd make a pretty cool candidate for Professor Moriarty, but 'Elementary' is certainly playing coy over when, if this season they'll introduce Sherlock Holmes' most classic foe.

Set to debut on CBS September 27 and starring Jonny Lee Miller and Lucy Liu, ‘Elementary’ will capitalize on the recent popularity of Sherlock Holmes, owing no doubt to both the popular Benedict Cumberbatch BBC series, as well as the big-screen iterations with Robert Downey Jr.   More than simply moving Holmes to the modern day, however, ‘Elementary’ will see a still-British Holmes operating in New York City, aided by his sober living companion, the notably female Joan Watson. 'Prime Suspect' star Aidan Quinn appears as Holmes’ NYPD liaison, while Jon Michael Hill ('Detroit 187') plays a police detective of the precinct.

What say you?  Do you think there's any more to Harbour's 'Elementary' role than meets the eye?  Tell us what you think, and let us know if you’ll be watching ‘Elementary’ this fall in the comments below!
