Another DC Comics TV show starts this week. “DC’s Stargirl” follows a high school student who decides to fight the bad guys. She teams up with her stepdad, a retired superhero, to create her own heroic team and take on villains from the past. The show, which is not set on the Arrowverse’s Earth-Prime, will stream on DC Universe and air on TV on The CW this week with a familiar cast.

Stargirl’s Family

Brec Bassinger stars as the titular Stargirl, AKA Courtney Whitmore, who made her first cameo in “Crisis on Infinite Earths” earlier this year. She’s a teenager who gets to join the Justice Society of America. The actress is recognizable to viewers from her roles on Nickelodeon’s “School of Rock” and Hulu’s “All Night.”

Amy Smart plays Stargirl’s mom, Barbara Whitmore, who is recently remarried and heading back into the workforce. Smart has been on screen for years in movies like “Just Friends” and “The Butterfly Effect” and TV shows such as “Maron” and “Justified.”

Luke Wilson plays Pat Dugan, Barbara’s new husband who has failed to mention his superhero past to her. Wilson has been in memorable films like “Legally Blonde,” “Old School” and “The Royal Tenenbaums.”

Trae Romano appears as Mike Dugan, Stargirl’s new stepbrother. Though he has appeared in miniseries like “Little Ghosts” and “555,” “Stargirl” is the newcomer’s biggest project yet.
