OMG HEROES.
For the most part, I try to avoid spoilers. But this was in TV Guide, so it doesn't count.
Claude, an invisible man played by British actor Christopher Eccleston (Doctor Who), appears January 22. "He's been living with his invisibility for many years and has come to grips with it, so he'll give us a different view into this hero world," Kring explains. "He's big, imposing and charismatic, and will become a mentor to Peter -- albeit a tough, reluctant and stern one. He'll help Peter learn to use and control his powers."
I enjoy the conglomeration of stuff I like: Peter Jackson directing Lord of the Rings, Steve Carell doing The Office, The Doctor on Heroes. Like how nachos are a combination of many individually-delicious pieces to make an extra-delicious whole when merged.
And that is some extra-delicious casting.
Edit: Demonstrating my nacho theory? Ed Helms is on the episode of Arrested Development I'm watching.
Edit 2: "I just blue myself." THAT NEVER GETS ANY LESS FUNNY.
