Glenn Close and Lance Henriksen reprise their roles as Kala and Kerchak from the first film while Harrison Chad, Brenda Grate, and Harrison Fahn are the new voices for the younger versions of Tarzan, Terk, and Tantor, replacing Alex D. Linz, Rosie O'Donnell, and Taylor Dempsey.
Taking place during Tarzan's youth and before his adulthood, the film follows Tarzan's adventure to discover who he really is.
