Nearly two years after saying goodbye to Chicago Fire, Kara Killmer is making her long-awaited return to acting. The actress will appear in Jimmy, a forthcoming biographical drama about James Stewart, starring KJ Apa in the lead role.
Killmer’s character, Lady Julia, is introduced as a singer performing for troops during wartime. In the film’s first trailer, she is shown captivating servicemen onstage before sharing intimate moments with Stewart near a military aircraft—hinting at a romantic arc woven into the story.
The project marks Killmer’s first role since she exited Chicago Fire early in Season 12. Her departure gave fans closure, with Sylvie Brett marrying Matt Casey and leaving Chicago to build a family in Portland. Though Casey has returned to the series, Brett has remained offscreen.
With Jimmy set for a November 6, 2026 release, Killmer’s return signals a new phase in her career—one that trades firehouse drama for historical romance and big-screen storytelling. For fans who’ve been waiting, her comeback is finally here.
