There has been a behind-the-scenes change at NBC’s Late Night With Jimmy Fallon as it prepares to morph into The Tonight Show in February. Former Daily Show executive producer/showrunner Josh Lieb is joining as producer, running day-to-day on Late Night and future Tonight Show, which are executive produced by Lorne Michaels. Lieb replaces veteran Late Night With Jimmy Fallon writer Amy Ozols, who will be leaving. She was named to the job in June. After a five-year stint on The Daily Show With Jon Stewart, where he rose to executive producer/showrunner, Lieb left in 2011 when he moved his family to Los Angeles to return to primetime series. Lieb had been considered for the Tonight Show Starring Jimmy Fallon job because of his late-night showrunner experience, but I hear he only recently became open to relocating back to New York where Late Night is based and so will be The Tonight Show. Lieb worked with Fallon just this past development season on an NBC comedy project, which Lieb co-created and Fallon produced through his company. Before The Daily Show, for which Lieb shared seven Emmy Awards, Lieb was a co-executive producer on The Simpsons and an executive producer on NewsRadio. He recently wrote and directed four comedic shorts for Matt Damon’s clean water and sanitation charity, water.org.
