<Li> Michael J. Fox as Milo James Thatch, a linguist and cartographer at the Smithsonian who was recruited to decipher The Shepherd's Journal while directing an expedition to Atlantis . Kirk Wise, one of the directors, said that they chose Fox for the role because they felt he gave his character his own personality and made them more believable on screen . Fox said that voice acting was much easier than his past experience with live action because he did not have to worry about what he looked like in front of a camera while delivering his lines . The directors mentioned that Fox was also offered a role for Titan A.E.; he allowed his son to choose which film he would work on, and he chose Atlantis . Viewers have noted similarities between Milo and the film's language consultant, Marc Okrand, who developed the Atlantean language used in the film . Okrand stated that Milo's supervising animator, John Pomeroy, sketched him, claiming not to know how a linguist looked or acted . </Li> <Li> James Garner as Commander Lyle Tiberius Rourke, the leader of the band of mercenaries, for the Atlantean expedition .

Kida's supervising animator, Randy Haycock, stated that Summer was very "intimidating" when he first met her; this influenced how he wanted Kida to look and act on screen when she meets Milo . Natalie Strom provided dialogue for Kida as a young child . </Li> <Li> Don Novello as Vincenzo "Vinny" Santorini, an Italian demolitions expert . Kirk Wise and Russ Edmonds, Vinny's supervising animator, noted Novello's unique ability to improvise dialogue .

And we never used a written line, it was improvs, the whole movie ." </Li>
