Reggie Wilson is an orchestra contractor who worked on 2009's Star Trek.  He previously worked with that film's composer, Michael Giacchino on the films Sky High, Mission: Impossible (which, like Star Trek, was directed by J.J. Abrams), and Ratatouille. He was also one of Giacchino's conductor on the video game Medal of Honor: Airborne.
Wilson has primarily contracted orchestras for the Buena Vista company. As such, he has worked on many films produced by the Walt Disney Company, including The Lion King (featuring the voices of Whoopi Goldberg and Madge Sinclair), Mulan (featuring the voices of Miguel Ferrer, Eddie Murphy, Freda Foh Shen, and George Takei), The Emperor's New Groove (featuring the voice of John Fiedler), The Jungle Book 2 (featuring the voices of Tony Jay and John Rhys-Davies), Chicken Little (featuring the voices of Wallace Shawn and Patrick Stewart), and the aforementioned Sky High and Ratatouille.
In addition, Wilson was a music contractor on several of Disney's direct-to-video sequels: The Return of Jafar (featuring the voice of Jason Alexander), Aladdin and the King of Thieves (featuring the voices of John Rhys-Davies and Robin Williams), Pocahontas II: Journey to a New World (featuring the voice of David Ogden Stiers), and The Little Mermaid II: Return to the Sea (featuring the voices of Rene Auberjonois, Clancy Brown, Kay E. Kuter, and Kenneth Mars). He also worked on two Winnie the Pooh direct-to-video movies, both featuring the voice of the aforementioned John Fiedler as Piglet: Pooh's Grand Adventure: The Search for Christopher Robin (narrated by David Warner) and Winnie the Pooh: Seasons of Giving.
Wilson's collaboration with Buena Vista also allowed him to work on several films from Touchstone Pictures, including 1993's What's Love Got to Do With It, 2003's Bringing Down the House (featuring Michael Ensign) and 2004's The Life Aquatic with Steve Zissou (featuring Seymour Cassel).
