Question: Are Frank Oz and Andrew Davis both puppeteers?
Context: Elliott Miles Goodman (August 27, 1948 – August 16, 1996) was an American composer for television and film.  He is best remembered for his frequent collaboration with film director Frank Oz, for whom Goodman scored such films as "Dirty Rotten Scoundrels" (1988), "What About Bob? " (1991) and "Housesitter" (1992).  For his score to Oz's "Little Shop of Horrors" (1986), Goodman was nominated for the Golden Globe Award for Best Original Score. The Oz books form a book series that begins with "The Wonderful Wizard of Oz" (1900) and relate the fictional history of the Land of Oz.  Oz was created by author L. Frank Baum, who went on to write fourteen full-length Oz books.  All of the Baum written books are in the public domain in the United States.  Even while he was alive, Baum was styled as "the Royal Historian of Oz" to emphasize the concept that Oz is an actual place.  The illusion created was that characters such as Dorothy and Princess Ozma related their adventures in Oz to Baum themselves, by means of wireless telegraph. The Muppets Take Manhattan is a 1984 American musical comedy film directed by Frank Oz.  It is the third of a series of live-action musical feature films starring Jim Henson's Muppets with special appearances by Art Carney, James Coco, Dabney Coleman, Gregory Hines, Linda Lavin, and Joan Rivers.  The film was produced by Henson Associates and TriStar Pictures, and was filmed on location in New York City during the summer of 1983 and released theatrically the following summer.  It was the first film to be directed solely by Oz (who also performs Sam the Eagle, Fozzie Bear, Miss Piggy, and Animal), as he previously co-directed "The Dark Crystal" with Henson. The Land of Ev is a fictional country in the Oz books of L. Frank Baum and his successors.  Its exact location is unclear between text and maps. " The Road to Oz" states that Ev is to the north of the Land of Oz, and in "Ozma of Oz", Princess Ozma of Oz and her procession enter the Munchkin Country and meet the King of the Munchkins upon leaving the palace at Evna, the capital city.  Subsequent books place Ev nearer to the Winkie Country, and the map on the endpapers of "Tik-Tok of Oz" shows the Munchkin Country as having no northern border with the desert that surrounds Oz, as a thin strip of the Gillikin Country extends even farther east than most of the Munchkin Country.  This map depicts Ev as a small country to the northwest (the compass rose is reversed) of Oz, with the Dominions of the Nome King as a separate area.  James E. Haff and Dick Martin's map, following the text, place the Nome Kingdom under an Ev that takes up the entire portion allotted to the Nome King's dominions on Baum's map. Bert and Ernie are two Muppets who appear together in numerous skits on the popular U.S. children's television show "Sesame Street".  Originated by Frank Oz and Jim Henson, the characters are currently performed by Muppeteers Eric Jacobson and Peter Linz; Oz occasionally performed Bert between 2000 and 2006. Grover, also known as Grover Monster, is a puppet character on the popular television show "Sesame Street".  Self-described as lovable, cute and furry, he is a blue monster who rarely uses contractions when he speaks or sings.  Grover was originally performed by Frank Oz from his earliest appearances.  Eric Jacobson began performing Grover in 1998; he has performed the character regularly since 2001, although Oz still performs him occasionally but not usually. Frank Oz (born Frank Richard Oznowicz; born May 25, 1944) is an English-born American puppeteer, filmmaker and actor.  His career began as a puppeteer, where he performed the Muppet characters of Miss Piggy, Fozzie Bear, Animal, and Sam Eagle in "The Muppet Show", and Cookie Monster, Bert, and Grover in "Sesame Street".  He is also known for being the puppeteer and voice of Yoda in the "Star Wars" films. Andrew Davis (born November 21, 1946) is an American film director, producer, writer, and cinematographer who is known for directing a number of successful action thrillers including "Code of Silence", "Above the Law", "Under Siege", and "The Fugitive". Bert is a yellow Muppet character on the long-running children's television show, "Sesame Street".  Bert was originally performed by Frank Oz.  Since 1997, Muppeteer Eric Jacobson has been phased in as Bert's primary performer, like Grover, although Frank Oz still performs Bert occasionally.  Bert has also made cameo appearances within "The Muppets" franchise, including "The Muppet Show", "The Muppet Movie", and "The Muppets Take Manhattan". The Swedish Chef is a Muppet character that appeared on "The Muppet Show".  He was originally performed by Jim Henson and Frank Oz simultaneously, with Henson performing the head and voice and Oz performing the character's live hands.  The Swedish Chef is currently performed by Bill Barretta.  His best known phrase is "Bork bork bork".
