Kevin Heffernan and Steve Lemme are best known for their work with the Broken Lizard comedy troupe, the group responsible for a string of comedy films in the 2000s, like the first Super Troopers and Beerfest, that shaped American comedic sensibilities at the movies for a decade. With their original truTV series Tacoma FD, however, Heffernan and Lemme wanted to do something a little different. The show premiered in late March and gradually gained a niche following that has resulted in some pretty good ratings for the network. Ahead of the season finale next Thursday, the longtime friends and collaborators spoke to Den of Geek about the inspiration for the series, its surprisingly familial themes, and more for The Fourth Wall podcast.
