They join Jim Parsons and Rihanna in the November 2014 release
Martin will voice Captain Smek, leader of the overly optimistic alien race known as the Boov, who take over Earth and begin to relocate the human race — convinced they're doing them a big favor.
Rihanna will voice a resourceful girl who avoids capture and unwittingly becomes the accomplice of a banished Boov (Parsons). Lopez will play the girl's mother.
Tim Johnson (“Over the Hedge,” “Antz”) is directing from a screenplay by Tom J. Astle and Matt Ember. Chris Jenkins and Suzanne Buirgy are producing; DreamWorks Animation development head Gregg Taylor will oversee for the studio.
Martin is repped by WME; Lopez is repped by CAA.
