'9-1-1: Lone Star' returns for its second season on Fox somewhat shaken up by the pandemic. One of its main stars, Liv Tyler, has had to drop out of the series due to coronavirus concerns, whose spot will be filled by a new character, played by Gina Torres. We take a look at some of the show's cast and where else you might have seen them in their acting careers.

Rob Lowe

Rob Lowe stars as Owen Strand, firefighter captain from New York City who moves to Austin, Texas with his son after losing his entire firehouse in the 9/11 Twin Tower attacks. Rob Lowe is a longtime Hollywood icon, who made his acting debut with the ABC sitcom 'A New Kind of Family'. From there, he quickly went on to become a member of the famed Hollywood "brat pack," as it was called, with roles in films such as 'The Outsiders', 'Class' and 'St. Elmo's Fire'. He is best known for his roles on 'The West Wing', 'Parks & Recreation' and 'Code Black'.
