Production has just begun on Travelers, a new Canadian-made sci-fi series set to air on Showcase later this year.

Former Will & Grace star Eric McCormack heads the cast of this shot-in-Vancouver drama created by Brad Wright, longtime exec producer of the wildly popular Stargate SG-1 franchise.

“Hundreds of years from now, the last surviving humans discover the means of sending consciousness back through time, directly into people in the 21st century,”; reads the official description for Travelers. “These “travelers’ assume the lives of seemingly random people, while secretly working as teams to perform missions in order to save humanity from a terrible future.”;

The travelers from the future are: FBI Special Agent Grant MacLaren (Eric McCormack), the team’s leader; Marcy (Mackenzie Porter), a young, intellectually disabled woman in the care of her social worker, David (Patrick Gilmore); Trevor (Jared Paul Abrahamson), a high school quarterback; Carly (Nesta Marlee Cooper), a single mom in an abusive relationship; and Philip (Reilly Dolman), a heroin-addicted college student.

“Armed only with their knowledge of history and an archive of social media profiles,”; the description continues, “the travelers discover that 21st century lives and relationships are as much a challenge as their high-stakes missions.”;

“Travelers joins Showcase’s critically acclaimed roster of hit dramatic series and we’re thrilled to work with such an esteemed group of Canadians to create this new, homegrown drama,” said Daniel Eves, Showcase’s Senior Vice President, Kids and General Entertainment Content, in a statement.

“My old friend Brad Wright has created a fantastic, complex story with some very rich and complicated characters,”; added star Eric McCormack, “and I’m awfully happy to be one of them.”;

Concluded Wright: “We’re thrilled to be working with Showcase and Netflix and are so proud that Travelers was originally developed at the CFC Prime Time TV Program with Canadian writers. We’re excited to work with this amazing cast led by Eric McCormack. It’s all a dream come true for a Scarborough boy like me.”;

Look for Travelers to debut on Showcase later this year.
