Bryan Cranston swung by Late Show With David Letterman last night to chat about the first half of the final season of Breaking Bad, which premieres this Sunday evening. As usual, Bryan couldn't reveal much of what we can expect when Walt, Jesse, and the rest of the crew returns, though he did shed some light on why Breaking Bad is ending after five seasons. From here, Bryan is off to San Diego for Comic-Con! The Breaking Bad panel is one of the most exciting Comic-Con events of the year and we're there to bring you all the action. Check out Bryan and Dave's chat and follow BuzzSugar on Twitter, Instagram, Facebook, and more for everything Breaking Bad at Comic-Con.
