Now he's moving on to Day One, NBC's series about global Armageddon. Has his Middle-optimism deserted him? We asked him. Minor spoilers ahead.Yesterday, we posted a leaked trailer for Day One, which starts airing in March on NBC. Grillo-Marxuach is joining the show as a co-executive producer, and he says that trailer is a "great teaser for what's happening in the show." It's actually the trailer that series creator Jesse Alexander made, to convince the network to pick the show up. Grillo-Marxuach says even though he's sad The Middleman was canceled, he's excited to move on with his career and get to work with another group of talented people and learn from them.
