Is irony a saving grace? Jon Stewart surely thinks so. He uses irony to channel his clear-eyed political fury on The Daily Show, and he’s directed a feature film that suggests irony is the only thing standing between us and madness. Rosewater is the reason Stewart disappeared from his late-night gig in the summer of 2013: He was in Jordan, directing a true story that has a stranger-than-fiction connection to The Daily Show. The movie is about the Iranian-Canadian journalist Maziar Bahari, played by Mexican star Gael García Bernal. In 2009 Bahari was arrested by Iranian authorities while covering the disputed elections in Tehran; included in the “evidence” against him was a Daily Show segment in which he joked with comedian Jason Jones about being a spy. Obviously, this was proof of espionage.
