There is just one episode left of Breaking Bad, with the 75-minute series finale "Felina" airing Sunday, September 29 at 9 PM ET. AMC has released a trailer for this highly-anticipated conclusion, featuring some of the intense moments leading up to this intense showdown. It's worth noting that the title "Felina" is both an anagram for the word "finale," and is also comprised of elements on the periodic table, "Fe" (Iron), "Li" (Lithium) and "Na" (Sodium). We'll have to wait and see if these specific elements are featured in the story. In addition, the network has released two behind-the-scenes featurettes from last night's "Granite State".
