Trivia: The character Steve Zissou, played by Bill Murray, is an homage to Captain Jacques-Yves Cousteau, who also wore a red wool cap identical to the caps worn by Zissou and his crew. Additionally, Captain Cousteau's ship was named Calypso, and in the film Zissou's ship is named Belafonte, a send-up because Harry Belafonte, a Jamaican American musician/actor, was referred to as the "King of Calypso."
Trivia: Steve's #1 intern is played by Matthew Gray Gubler. Gubler was actually an intern for director Wes Anderson during production, and Anderson liked him so much, he gave him a role in the film.
