Justin Hartley shifts gears in new drama "Tracker"

Actor Justin Hartley, known for his role as Kevin Pearson on "This Is Us," has taken on a drastically different character in the new CBS action-packed drama series "Tracker." Hartley stars as Colter Shaw, a rugged survivalist who traverses the country to locate missing people and collect rewards.

Hartley said he had to completely depart from Pearson to prevent any overlap between the characters. 

"I didn't want Kevin leaking out into what I was doing for Colter. So I actually made a list of the two of them. And it turns out they have nothing in common," he told "CBS Mornings."
