Background: Walston was born Herman Raymond Walston on November 2, 1914, in Laurel, Mississippi, the second son and youngest of three children born to lumberjack Harry Norman Walston (1881-1946) and Mittie (nee Kimball) Walston (December 25, 1883-August 16, 1950). He had an older sister, Carrie (1906-1982), and an older brother, Earl (February 4, 1908 - December 4, 1998). His family moved from Mississippi to New Orleans, Louisiana around 1925. He started acting at an early age, beginning his tenure as a spear carrier rounding out productions at many New Orleans theaters.
Context: From 1980-1992, Walston starred in 14 films, including Galaxy of Terror and Fast Times at Ridgemont High (as well as the 1986 television adaptation) as Mr. Hand. In a 1999 interview, Walston said that he was happy and relieved that when he walked down the street, young fans shouted at him "Mr. Hand" because he had finally torn away from his Martian role. In 1984, Walston played a judge on an episode of Night Court. Six years later, he made a guest appearance on an episode of L.A. Law. He later was hired for the role of Judge Henry Bone on Picket Fences; the character was originally a recurring role, but Walston proved to be so popular the character was later upgraded to a starring role.  He made an appearance in Star Trek: The Next Generation as Boothby, head groundskeeper at Starfleet Academy in San Francisco, and he reprised the character twice on Star Trek: Voyager, despite the series being set in a distant part of the galaxy. (The first time, he actually played an alien participating in a simulation of the Academy; the second appearance was in a dream sequence.) During his appearance on Star Trek: Voyager in "In the Flesh", he often had trouble with remembering his lines during long one-shot dialogue scenes, but while the cameraman was changing the film for the scene in the briefing room, he quoted a line from Hamlet. Robert Beltran then quoted the next line, and Walston the next. The two went on for several minutes, amazing the entire cast and crew. In a twist of fate Beltran had starred in the role of Luther Billis while in high school  In 1985, Walston made a brief appearance in the opening credits of Steven Spielberg's series Amazing Stories, as a caveman acting out a story for his tribe. Only a few seconds long, this performance began every episode of the subsequent series. In 1992, Walston played the role of Candy in the big-screen remake of John Steinbeck's Of Mice and Men with Gary Sinise and John Malkovich. He would work alongside Sinise again two years later in the miniseries adaptation of Stephen King's The Stand.  Walston was nominated three times for Best Supporting Actor in a Drama Series for his work on Picket Fences, winning twice, in 1995 and 1996. CBS cancelled the show after four seasons in 1996. Walston made a guest appearance in an episode of Dr. Quinn, Medicine Woman entitled "Remember Me", in which he portrayed the father of Jake Slicker, who was stricken with Alzheimer's disease.
Question: What role did he play?
Answer: 

Problem: Background: Jesse Donald Knotts was born in Morgantown, West Virginia, the youngest of four sons born to farmer William Jesse Knotts and his wife, Elsie Luzetta Knotts (nee Moore). His parents were married in Spraggs, Pennsylvania. His English paternal ancestors immigrated to America in the 17th century, originally settling in Queen Anne's County, Maryland. Knotts' brothers were named Willis, William, and Ralph.
Context: In 1960, Andy Griffith was offered the opportunity to headline his own sitcom, The Andy Griffith Show (1960-1968). Knotts took the role of Barney Fife, the deputy--and originally cousin--of Sheriff Andy Taylor (portrayed by Griffith). Knotts's portrayal of the deputy on the popular show earned him five Emmy Awards for Best Supporting Actor in a Television Comedy, three awards for the first five seasons that he played the character.  A summary of the show from the website of the Museum of Broadcast Communications describes Deputy Barney Fife:  Self-important, romantic, and nearly always wrong, Barney dreamed of the day he could use the one bullet Andy had issued to him, though he did fire his gun on a few occasions. He always fired his pistol accidentally while still in his holster or in the ceiling of the court house, at which point he would sadly hand his pistol to Andy. This is why Barney kept his one very shiny bullet in his shirt pocket. In episode #196, Andy gave Barney more bullets so that he would have a loaded gun to go after a bad guy that Barney unintentionally helped escape. While Barney was forever frustrated that Mayberry was too small for the delusional ideas he had of himself, viewers got the sense that he couldn't have survived anywhere else. Don Knotts played the comic and pathetic sides of the character with equal aplomb and he received three Emmy Awards during the show's first five seasons.  When the show first aired, Griffith was intended to be the comedic lead with Knotts as his straight man, similar to their roles in No Time for Sergeants. However, it was quickly discovered that the show was funnier with the roles reversed. As Griffith maintained in several interviews, "By the second episode, I knew that Don should be funny, and I should play straight."  Knotts believed remarks by Griffith that The Andy Griffith Show would end after five seasons, and he began to look for other work, signing a five-film contract with Universal Studios. He was caught off guard when Griffith announced that he would continue the show after all, but Knotts's hands were tied. In his autobiography, Knotts admitted that he had not yet signed a contract when Griffith announced his decision; but he had made up his mind to move on, believing he would not get the chance again. Knotts left the series in 1965. His character's absence on the show was explained by Deputy Fife's having finally made the "big time," joining the Raleigh, North Carolina police force.
