King Julien voice: Which actor played him in the Madagascar films?

CLIPS on Instagram: "🦁 Interesting fact: In “Madagascar”, the actors recorded so many chaotic improvisations that the animators sometimes had to redesign facial expressions to match whatever wild energy the voice actors brought that day. Chris Rock and Ben Stiller kept cracking each other up in the booth, and half the scenes only exist because the cast couldn’t stay serious for more than ten seconds."
