Tracker gives Justin Hartley the ability to play out a lot of different stories - but there are certain plot lines he isn't interested in doing. During an exclusive interview with Us Weekly, executive producer Elwood Reid weighed in on Hartley's recent comments about Colter possibly dying and how it relates to how the show portrays the main character, saying, "It is funny. He says it all the time. Going back to what I think makes the show is that he's not Superman." Reid noted it was important to keep Colter a grounded character.
