Joshua Keaton, formerly Joshua Wiener, portrayed the voice of Jules Brown on Back to the Future: The Animated Series. Keaton, born on February 8, 1979, could be seen on camera in various roles, most notably on the Nickelodeon TV series The Secret World of Alex Mack, and later in some episodes of the soap opera The Young and the Restless. Most of his work has been as a voice actor.
In 2002, Keaton originally voiced the title character of the video game Spider-Man: The Game based off the 2002 Spider-Man film. Tobey Maguire, however, came aboard to voice the character. As a result, Keaton's voice work was modified into the character Harry Osborn/The Second Green Goblin.
He also reprised his role as Harry Osborn again (this time going by The New Goblin) in the video game Spider-Man: Friend or Foe which had Taylor voicing the title character. Roger Jackson provided the voices of both The Green Goblin and Lizard, as well as Alaskey voicing Doctor Octopus in the game as well.
In 2010, Keaton, along with Wilson and Taylor provided voice work for the video game, Spider-Man: Shattered Dimensions. He also provided the voices for The Flash and Aquaman in the DTV Justice League: Crisis on Two Earths which was written by Dwayne McDuffie.
Also, Keaton and Taylor respectively provided the voices of Young Hercules (who Keaton voiced in the 1998 animated movie Hercules) and The Prince (Snow White) in the video game Kingdom Hearts: Birth By Sleep.
In 2012, Keaton reprised the role of Spider-Man in several episodes of The Avengers: Earth's Mightiest Heroes (one of which had guest starred David Kaufman as Johnny Storm/The Human Torch), but the studio decided to dub his lines over prior to broadcast.
In 2016, Keaton voiced the LEGO Dimensions character Gamer Kid, entrusted to protect the denizens of Midway Games from evil forces. Some of his dialogue references Back to the Future, such as when he asks if he needs a license to drive the DeLorean time machine "back to the future", and when he asks Marty McFly (voiced by Michael J. Fox), "Shouldn't you be out collecting clocks?"
