The Jay Leno Show is fleshing out its non-Leno roster: Ross Mathews (formerly known as Ross the Intern) and comedians Brian Unger, Nick Thune, Owen Benjamin, Marina Franklin and Sebastian Maniscalco join the previously announced Liz Feldman, D.L. Hughley, Mikey Day, Rachael Harris, Jim Norton, and Dan Finnerty and The Dan Band as “correspondents.” (Feldman was listed in NBC’s press release today, but her participation was announced last month.) The correspondents will provide field reports and sketches when the show premieres Sept. 14.
