Fans of Smallville and the "Arrowverse" are going to like what Tracker has in store for an upcoming episode. Matt Webb Mitovich's "Matt's Inside Line" (which has some great updates and an email update you can subscribe to) is reporting exclusively that Erica Durance (Lois Lane on Smallville) and David Ramsey (John Diggle, "Arrowverse") will join Hartley for the March 22nd episode. Durance's Laura is "an accomplished stunt woman" who enlists Colter (Hartley) "after her boyfriend Baxter disappears without a trace from a film set." Ramsey's Baxter is described as "a weathered veteran stuntman with a list of injuries as long as your arm. Finding "his star fading," Baxter is "reduced to working low-budget indie films to make ends meet," the character description continues. Along with the Smallville and "Arrowverse" connections with Durance and Ramsey, let's not forget that Hartley joined Smallville during the sixth season as Oliver Queen, aka Green Arrow. And then there's the not-so-small matter of how the "Smallville" universe appeared during the "Crisis on Infinite Earths" that hit the "Arrowverse" back in 2019, but that's a whole other story.

Justin Hartley is back as lone-wolf survivalist Colter Shaw in CBS's Tracker. Following last season's explosive finale, Colter is wrestling with hard truths about his family's history. In the wake of these shocking revelations, and aided by his trusted team, Colter must put the past in the rearview to focus on what he does best: using his instincts and survival skills to find the missing and collect rewards. Also starring Fiona Rene (Reenie Greene), CBS's Tracker is executive-produced by Hartley, Reid, Ken Olin, Connie Dolphin, Sharon Lee Watson, and Alex Katsnelson.
Kathleen Robertson (The Expanse, Swimming with Sharks) and Mark Engelhardt (American Horror Story, NCIS) have joined the cast in recurring roles. Robertson's Maxine is described as "a successful attorney at a major firm looking to engage Reenie (Fiona Rene) on what Maxine assures her is simply grunt work for an upcoming class action suit. It quickly becomes clear, however, that Maxine may have an entirely different game that she's playing." Meanwhile, Engelhardt's Emile Lang is described as "a man with his own moral code" who is "cold, calculating, and methodical."
