When Morgan Spurlock shot to fame, he was gorging himself on McDonald's three times a day to see what happens if he lived off only that -- and he ate the largest size that workers pushed -- in "Super Size Me."

In "Futurism," airing Sunday, April 20, Spurlock focuses on those striving for immortality. Since shooting that episode, Spurlock has lost 25 pounds.

He attends a party in California where people try various ways to extend their lives. Some take hundreds of supplements daily; others are on the paleo diet.

It would be a stronger show if Spurlock asked more questions such as: Why eat like a caveman? Why take so many vitamins? Spurlock has an incredibly thorough physical exam, and the doctor tells him to shed 18 pounds, take supplements and exercise.

Spurlock's goal is "to delve into issues that affect all of us, maybe in ways we don't even realize," he says. "A lot of times we see headlines and think they don't affect us. What the show does a great job of doing is showing how they do affect us."

Last week's Season 2 premiere was devoted to celebrity. Spurlock tried to be a paparazzo. Unless you're Angelina, Jen or a successful actor who dares to take the children to the playground, it's hard to see how paparazzi affect most people.

"What a lot of people don't realize is every time you buy a People, an Us, a Star, it does touch you," Spurlock says. "As you turn on the TV and watch 'TMZ' or 'Access Hollywood,' people are complicitly involved without recognizing their involvement."

Additional episodes look at religion, UFOs and paying student athletes.
