What is Jesse Spencer doing now?

Guest appearance on Chicago Fire

After leaving as a series regular, Spencer returned for a guest appearance in Season 11, Episode 18 of Chicago Fire. In an interview with The Chicago Sun-Times (local news outlet), he explained that his character Matt Casey — now living in Oregon — was still part of the story, and he wanted to help wrap up threads. The episode aired in April 2023.

Focus on music and family

Spencer married neuroscientist Kali Woodruff Carr in 2020, and the couple welcomed a child shortly after. In a 2023 interview, he said his priorities shifted: “Being a dad changed everything. I wanted to be present.” He also spent time on music, a passion he has pursued since his House days.

Public appearances

Spencer continues to make occasional public appearances at fan conventions and charity events. He has not taken on a new regular television role since leaving Chicago Fire, but he completed filming the Australian series Last Days of the Space Age in 2024, according to WHO Australia (entertainment magazine).

The pattern: Spencer’s career pivot reflects a deliberate choice to prioritise personal life over constant screen time.

Why did Jesse leave Chicago Fire?

Creative reasons for leaving

Spencer told NBC Insider (the network’s official behind-the-scenes platform) that after 18 years in network television — nine on House and nine on Chicago Fire — he felt it was time to move on. “I’d been doing this for a long time,” he said. “I wanted to do other things.” He called showrunner Derek Haas to express his desire to exit, and they agreed that his character would reach the 200th episode milestone first.

Contractual factors

While Spencer never publicly discussed contract disputes, Newsweek (news magazine) reported that his departure was amicable. The showrunner and network supported his decision, and the door was left open for returns. The exit was described as personal rather than conflict-driven, as noted by CBR (comic and pop culture site).

Character outcome

In the story, Captain Matt Casey moved to Oregon to become the legal guardian of his late best friend’s sons. People (celebrity news outlet) confirmed that the character’s exit was written to allow for future returns, which Spencer later took advantage of in 2023.

The implication: Spencer’s amicable exit sets a precedent for actors seeking graceful transitions.
