Morgan Spurlock, Documentarian Known for ‘Super Size Me,’ Dies at 53

Morgan Spurlock, a documentary filmmaker who gained fame with his Oscar-nominated 2004 film “Super Size Me,” which followed him as he ate nothing but McDonald’s for 30 days — but later stepped back from the public eye after admitting to sexual misconduct — died on Thursday in New York City. He was 53.

His brother Craig Spurlock said the cause was complications of cancer.

A self-described attention hound with a keen eye for the absurd, Mr. Spurlock was a playwright and television producer when he rocketed to global attention with “Super Size Me,” an early entry into the genre of gonzo participatory filmmaking that borrowed heavily from the confrontational style of Michael Moore and the up-close-and-personal influences of reality TV, which was then just emerging as a genre.

The film’s approach was straightforward: Mr. Spurlock would eat nothing but McDonald’s food for a month, and if a server at the restaurant offered to “supersize” the meal — that is, to give him the largest portion available for each item — he would accept.

The movie then follows Mr. Spurlock and his ever-patient girlfriend through his 30-day odyssey, splicing in interviews with health experts and visits to his increasingly disturbed physician. At the end of the month, he was 25 pounds heavier, depressed, puffy-faced and experiencing liver dysfunction.

The film, which debuted at the Sundance Film Festival, grossed over $22 million, made Mr. Spurlock a household name, earned him an Academy Award nomination for best documentary and helped spur a sweeping backlash against the fast-food industry — though only temporarily; today, McDonald’s has 42,000 locations worldwide, its stock is near an all-time high, and 36 percent of Americans eat fast food on any given day.
