Casting directors are making their way to the metro area on a 13-city nationwide tour to find participants for Season 4 of "Extreme Makeover: Weight Loss Edition."

On April 20, officials will set up shop at Metro Center Mall off Highway 80 in Jackson as they search to find people to fill 15 slots of people they categorize as "super obese."

Season 3 will soon air as camera crews followed New York Times bestselling author and fitness guru Chris Powell over a year in his effort to transform the lives of 15 obese people across the country.

Officials are asking those interested in applying to first visit www.extrememakeovercasting.com.

Those that attend the casting call from 10 a.m.-5 p.m. should bring a non-returnable photo.
