The Top 20 returned this season in contrast to the previous season's Top 11. Mary Murphy also returned as a main judge to replace Mia Michaels, who was absent during Season 7 due to contract issues and surgery. Adam Shankman was unavailable to return as a main judge due to him directing Rock of Ages. In his place were guest judges Lil' C, Tyce Diorio, Jason Gilkison, Toni Redpath, and Robin Antin. This season was also the first time viewers were given the chance to vote online.
