Following the success of “9-1-1,” FOX is expanding on the franchise with its newest series, “9-1-1: Lone Star,” and fans may be surprised with just how well they know the actors bringing the new drama series’ characters to the small screen.

Following the success of “9-1-1,” which premiered in 2018 and told the stories of first responders in Los Angeles, FOX decided to build on the franchise with a new setting and some new faces with “9-1-1: Lone Star.” The show follows the same concept as its predecessor, with a synopsis stating that “a sophisticated New York cop, along with his son, relocates to Austin and must try to balance the duties of saving those who are at their most vulnerable and solving problems in his own life.”

Also similar to the original show, “Lone Star” is no stranger to bringing in an impressive cast. Check out the stars of this new series below.
