Zissou's crew aboard his research vessel Belafonte includes Pelé dos Santos (Seu Jorge), a safety expert and Brazilian musician who sings David Bowie songs in Portuguese; Klaus Daimler (Willem Dafoe), a lovable German second-in-command who views Zissou and Esteban as father figures and feels threatened by Zissou's possible son, Ned Plimpton (Owen Wilson).
