BEST IMAGE. He’s also Dr. Emil Skoda in Law & Order. And, my favorite, Vern Schillinger in Oz.
I still can’t get over the fact that Tenzin in Legend of Korra is voiced by the same guy that does the annoying J. Jonah Jameson in Ultimate Spider-Man.
And now you can’t unsee it either.
Don’t forget that he is also another fantastic and memorable character who has contributed a lot to science involving portals and mantis DNA.
