Tom McGrath explained that `` Ben Stiller was the first actor we asked to perform , and we knew we wanted his character , Alex , to be a big performing lion with a vulnerable side . '' </Li> <Li> Chris Rock as Marty , a zebra . McGrath explained the character : `` Marty is a guy who thinks there might be more to life than what 's in the zoo . We wanted his character to be energetic , so we listened to Chris Rock . '' </Li> <Li> David Schwimmer as Melman , a hypochondriac giraffe who is afraid of germs . When they were looking for a voice actor for Melman , they listened to Schwimmer 's voice on Friends and , according to McGrath , thought that it `` sounded really neat .

Stack was approached about voicing the character , but died two weeks before production on the animation began . After that , DreamWorks Animation CEO Jeffrey Katzenberg decided to keep the temporary voice , with McGrath explaining : `` People were used to me doing that voice . We knew it worked when we screened it . '' Many character 's traits were based on Stack 's work .
