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

Morgan Spurlock, a documentary filmmaker best known for the Oscar-nominated 2004 film “Super Size Me,” which followed him as he ate nothing but McDonald’s for 30 days, died on Thursday. He was 53.

His brother Craig Spurlock confirmed the death in a statement to The Associated Press, and said the cause was complications from cancer. The statement did not say where he died.

In “Super Size Me,” Mr. Spurlock tested the broadly held idea that fast food is unhealthy by gorging on McDonald’s Super Size meals, hamburgers, fries, soda and more for weeks, as he steadily gained weight. The film, which grossed more than $22 million on a $65,000 budget, contributed to a sweeping backlash against the fast food industry.
