Ernie Fosselius
From Wookieepedia, the Star Wars wiki.
Ernie Fosselius voiced Malakili and Giran in Star Wars Episode VI: Return of the Jedi. He also served as the music arranger for the film. Sound designer Ben Burtt asked Fosselius to record the sobs of the rancor, and he reportedly based the sound on Stan Laurel. In addition, he did sound effects for Poggle the Lesser.
He also worked on the Star Wars parodies Hardware Wars and Spaceballs. Both Hardware Wars and Porklips Now, a parody of Apocalypse Now, is available at Caachi - http://caachi.com
