O'Connell will play Sheriff Dan Lamb, the younger brother of Don Lamb (Michael Muhney), who died in Season 3.
O'Connell joins a large roster of returning cast members including Ryan Hansen, Krysten Ritter, Tina Majorino, Sam Huntington, Chris Lowell, Jason Dohring in addition to star Kristen Bell. Bell, and series creator Rob Thomas, launched a Kickstarter fundraising page for the project back in March. It has since raised more than $5 million.
O'Connell can next be seen in CBS' new comedy We Are Men this fall.
