Question: Are J. G. Farrell and James Thurber both authors ?
Context: A Thurber Carnival is a revue by James Thurber, adapted by the author from his stories, cartoons and casuals (humorous short pieces), nearly all of which originally appeared in "The New Yorker".  It was directed by Burgess Meredith.  Following a six city tryout, during which Thurber continued to rewrite the show, it premiered on Broadway on February 26, 1960, and ran for 223 performances, with a break from June 25 to September 5.  It closed on November 26, 1960.  The title is similar to that of "The Thurber Carnival" (1945), Thurber's most successful collection of stories and drawings. "The Unicorn in the Garden" is a short story written by James Thurber.  One of the most famous of Thurber's humorous modern fables, it first appeared in "The New Yorker" on October 21, 1939; and was first collected in his book "Fables for Our Time and Famous Poems Illustrated" (Harper and Brothers, 1940).  The fable has since been reprinted in "The Thurber Carnival" (Harper and Brothers, 1945), "James Thurber: Writings and Drawings" (The Library of America, 1996, ISBN  ), "The Oxford Book of Modern Fairy Tales", and other publications.  It is taught in literature and rhetoric courses. James Grover Thurber (December 8, 1894 – November 2, 1961) was an American cartoonist, author, humorist, journalist, playwright, and celebrated wit.  He was best known for his cartoons and short stories published mainly in "The New Yorker" magazine, such as "The Catbird Seat," and collected in his numerous books.  He was one of the most popular humorists of his time, as he celebrated the comic frustrations and eccentricities of ordinary people.  He wrote the Broadway comedy "The Male Animal" in collaboration with his college friend Elliott Nugent; it was later adapted into a film starring Henry Fonda and Olivia de Havilland.  His short story "The Secret Life of Walter Mitty" has been adapted for film twice, once in 1947 and again in 2013. "The Secret Life of Walter Mitty" (1939) is a short story by James Thurber.  The most famous of Thurber's stories, it first appeared in "The New Yorker" on March 18, 1939, and was first collected in his book "My World and Welcome to It" (Harcourt, Brace and Company, 1942).  It has since been reprinted in "James Thurber: Writings and Drawings" (The Library of America, 1996, ISBN  ), is available on-line on the "New Yorker" website, and is one of the most anthologized short stories in American literature.  The story is considered one of Thurber's "acknowledged masterpieces".  It was made into a 1947 movie of the same name, with Danny Kaye in the title role, though the movie is very different from the original story.  It was also adapted into a 2013 film, which is again very different from the original. "The Princess and the Tin Box" is a short story by James Thurber in the form of a modern fable.  It was first published in the September 29, 1945 edition of "The New Yorker" magazine and republished in 1948 in Thurber's "The Beast in Me and Other Animals: A New Collection of Pieces and Drawings about Human Beings and Less Alarming Creatures".  The story is widely used as a text in schools for teaching both writing skills and reading comprehension. "The Rabbits who caused all the Trouble" is a short modern fable written by James Thurber.  It first appeared in "The New Yorker" on August 26, 1939; and was first collected in his book "Fables for Our Time and Famous Poems Illustrated" (Harper and Brothers, 1940).  The fable has since been reprinted in "The Thurber Carnival" (Harper and Brothers, 1945), "James Thurber: Writings and Drawings" (The Library of America, 1996, ISBN  ), "The Oxford Book of Modern Fairy Tales", and other publications.  The story is often used in classes that teach English as a second language.
