Did food or drugs bring Elvis' reign to an end?

While many rock stars meet an unfortunate end due to drug use, one man is taking a new look at Elvis Presley's death and what caused it. Was it drugs that did him in, or burgers?

James Marsh's new documentary, The Burger and the King, takes a look at Elvis' eating habits, starting with his poor, burgerless childhood and chronicling his love of fatty foods throughout his adult life. Fat and calorie content are included. A Southern boy through and through, the King was drawn toward unhealthy, fried and fatty foods, and his hunger seemed to grow right along with his fame.

The documentary will premiere at the IFC Center's Stranger Than Fiction festival, but you can also catch it on You Tube if you're so inclined.
