I just spoke with my friend last night, who I SWEAR they made the show around. I cannot speak of his BADNESS, but it was UP THERE with our own Bryan Cranston.
Most of the time, he is just a machine shop/phsyed teacher. Same brilliance, same LOOK exactly(twins) and well, its his favourite show of all time, eclipsing his previous favourite(and mine) Deadwood.
I so miss the lab underground though. That was just amazing.
