Daniel Louis "Dan" Castellaneta is an American actor, voice actor, comedian, and screenwriter who is best known for voicing Homer Simpson, Krusty the Clown, Groundskeeper Willie, and many other characters in the popular Fox animated sitcom The Simpsons, which he has continued to do since Disney's acquisition of Fox. He also voiced Lazaar in Sonic the Hedgehog (Sonic SatAM), Jonathan Kraskell in the Nickelodeon series Rugrats, and the titular character in the animated TV series Earthworm Jim, based on the video game of the same name.
Castellaneta has also done voice-over work in numerous Disney productions, most notably providing the voice of Genie in the Aladdin franchise whenever Robin Williams was unavailable and Megavolt in Darkwing Duck.

- Castellaneta was originally supposed to reprise his role of the Genie from The Return of Jafar and the Aladdin TV show in the second sequel of Aladdin, Aladdin and the King of Thieves. Although he recorded all his lines, when Disney brought back Robin Williams, all recordings made by Castellaneta went unused and new recordings by Williams were used.
