Jesse Spencer, best known for portraying Matthew Casey on Chicago Fire, has a storied acting career that spans decades, mediums, and continents. While fans of the One Chicago universe know him as the dedicated firefighter and former Truck 81 lieutenant at Firehouse 51, Spencer’s acting journey began long before his NBC debut. From Australian soap operas to Hollywood films and hit American TV dramas, Spencer has worn many hats throughout his career.
From Australian Soaps to Stardom
Jesse Spencer got his big break in the Australian soap opera Neighbors, where he played Billy Kennedy, a recurring character from 1994 to 2000. His portrayal of the son in the affluent Kennedy family made him a household name in Australia, with a whopping 461 episodes under his belt. Spencer briefly returned to the role in 2005, but during his time on Neighbors, he also explored other projects.
One of his earliest forays outside the soap was voicing Young Triton in Disney’s animated Hercules series. Sharing the stage with voice actors like Jason Alexander and James Woods, this role showcased his versatility early on.
Olsen Twins and Early Hollywood Roles
After leaving Neighbors, Spencer dabbled in TV movies and direct-to-video films, including Winning London (2001), where he played Lord James Browning, Jr., a love interest for one of the Olsen twins. This rom-com introduced him to a younger audience, while his role in Lorna Doone (2000) demonstrated his ability to adapt to more classical and dramatic storylines.
In 2003, Spencer gained attention as a supporting character in Uptown Girls, starring Brittany Murphy and Dakota Fanning. While the film received lukewarm reviews, it marked Spencer’s growing recognition in Hollywood. That same year, he played Australian swimmer Tony Fingleton in Swimming Upstream, solidifying his reputation as a versatile actor.
Making Waves in House, M.D.
Spencer’s breakthrough in the U.S. came in 2004 when he joined the cast of House, M.D. as Dr. Robert Chase. For eight seasons and 170 episodes, Spencer portrayed the ambitious and complex young doctor, often serving as a foil to the brash and brilliant Dr. Gregory House (Hugh Laurie). The critically acclaimed medical drama was a massive hit, and Spencer’s role made him a household name in the U.S.
During his tenure on House, the show received glowing reviews, with a 96% audience score on Rotten Tomatoes. Spencer’s nuanced performance as Chase earned him praise for bringing depth to a character navigating personal and professional struggles.

In 2012, Jesse Spencer swapped his lab coat for firefighter gear, taking on the role of Matthew Casey in Chicago Fire. As a key player in the Dick Wolf-created One Chicago universe, Spencer’s Casey became a beloved figure. His leadership, courage, and complicated love life, particularly his relationship with Sylvie Brett, endeared him to fans.
Beyond Chicago Fire, Spencer reprised his Casey role in crossover episodes with Chicago P.D. and Chicago Med. These appearances allowed him to connect with audiences across the franchise, further cementing his legacy within the One Chicago universe.
