Breaking Bad Built A Cabin 10,000 Feet Up A Mountain For Season 5

As the episode wears on, Walt is too restless to heed Ed's advice, stewing about the wrongs done to him by Jack's (Michael Bowen) gang and plotting ways to try and get money back to his wife and children in Albuquerque. Walt doesn't handle the solitude well, and his seething rage gets the better of him and he heads back to New Mexico to get his revenge in the series finale, "Felina."

In the featurette, series co-creator Peter Gould commented that "Granite State" marked Walt's slide from feared criminal mastermind to pitiable dying husk of a man. "This is the moment where we transform Walt from the Walt that we've been following to the Walt that we've seen in the future," Gould said. 

Makeup department head Tarra Day explained the physical mechanisms her team used to make that transformation. "We are using some silicone cheek pieces," Day said. "We have a neck piece, he looks a little paler, so he really looks like the cancer's really starting to play a big role in making him not feel good."
