Early in his career, Joe Flannigan took on small roles, including appearances in TV movies like the Danielle Steel adaptation Family Album. He also had a multi-episode arc on the family-focused drama Sisters, which helped him gain more visibility. From there, Joe Flannigan continued building his resume with various guest spots and minor recurring roles across different television shows—steady work that eventually led to his big break.
That break came when he was cast as Lt. Colonel John Sheppard in Stargate Atlantis, the widely popular follow-up to the cult classic Stargate SG-1.
