Problem: Background: Garland was born Frances Ethel Gumm on June 10, 1922, in Grand Rapids, Minnesota. She was the youngest child of Ethel Marion (nee Milne) and Francis Avent "Frank" Gumm. Her parents were vaudevillians who settled in Grand Rapids to run a movie theater that featured vaudeville acts. She was of Irish, English, and Scottish ancestry, named after both of her parents and baptized at a local Episcopal church. "
Context: In 1938, she was cast in her most memorable role, as the young Dorothy Gale in The Wizard of Oz (1939), a film based on the 1900 children's book by L. Frank Baum. In this film, she sang the song with which she would be identified, "Over the Rainbow". Although producers Arthur Freed and Mervyn LeRoy had wanted her from the start, studio chief Mayer first tried to borrow Shirley Temple from 20th Century Fox, but they declined. Deanna Durbin was then asked, but was unavailable, resulting in Garland being cast.  Garland was initially outfitted in a blonde wig for the part, but Freed and LeRoy decided against it shortly into filming. Her blue gingham dress was chosen for its blurring effect on her figure, which made her look younger. Shooting commenced on October 13, 1938, and was completed on March 16, 1939, with a final cost of more than US$2 million. With the conclusion of filming, MGM kept Garland busy with promotional tours and the shooting of Babes in Arms, directed by Busby Berkeley. Rooney and she were sent on a cross-country promotional tour, culminating in the August 17 New York City premiere at the Capitol Theater, which included a five-show-a-day appearance schedule for the two stars. Garland was forced into a strict diet during filming; she was given tobacco to suppress her appetite.  The Wizard of Oz was a tremendous critical success, though its high budget and promotions costs of an estimated $4 million (equivalent to $70.4 million in 2018), coupled with the lower revenue generated by discounted children's tickets, meant that the film did not make a profit until it was rereleased in the 1940s and in subsequent rereleases. At the 1939 Academy Awards ceremony, Garland received her only Academy Award, a Juvenile Award for her performances in 1939, including The Wizard of Oz and Babes in Arms. Following this recognition, she became one of MGM's most bankable stars.
Question: What was The  Wizard of Oz based on ?
Answer: a film based on the 1900 children's book by L. Frank Baum.

Problem: Background: Frasier Winslow Crane is a fictional character on the American television sitcoms Cheers and Frasier, portrayed by Kelsey Grammer. Grammer received award recognitions for portraying this character in these two shows, in addition to a 1992 one-time appearance in Wings. The character debuts in the Cheers third-season premiere, "Rebound (Part 1)" (1984), as Diane Chambers's love interest, part of the Sam and Diane story arc. Intended to appear for only a few episodes, Grammer's performance for the role was praised by producers, prompting them to expand his role and to increase his prominence.
Context: In 1993, after Cheers ended, Frasier and Lilith (Bebe Neuwirth) divorce offscreen, and Lilith is awarded custody of their son Frederick, with Frasier granted visiting rights. In the pilot "The Good Son", Frasier explains that he left Boston because he felt that his life and career had grown stagnant (and he had been publicly humiliated after climbing onto a ledge and nearly committing suicide before being talked down). Therefore, he returned to his original hometown of Seattle, where his father Martin (John Mahoney) and brother Niles (David Hyde Pierce) live, to begin a fresh start.  Frasier works for the radio station, KACL, as the host of his psychotherapeutic radio show, The Dr. Frasier Crane Show, produced by his producer and friend, Roz Doyle (Peri Gilpin), who has many ex-boyfriends. Later, his father Martin, a retired Seattle Police Department detective who was shot in the line of duty, ends up moving in with him. Frasier becomes concerned about his father in his current state as he can barely walk, and requires a cane to move. In Cheers, Frasier says that his father is dead, and that he was a scientist. He also says that he is an only child. This inconsistency is later explained in "The Show Where Sam Shows Up": At Frasier's apartment, Sam Malone tells Martin and Niles what Frasier had said about them, and Frasier explains that he was trying to distance himself from his family at the time. In Cheers, Frasier tells bar patrons that he is an orphan. He confirms in "To All the Girls I've Loved Before" (1988) that his mother Hester, portrayed by Nancy Marchand in "Diane Meets Mom" (1984) and then by Rita Wilson in flashbacks in "Mamma Mia" (1999) and "Don Juan in Hell: Part 2" (2001), is dead off-screen.  Frasier hires a live-in physical therapist, Daphne Moon (Jane Leeves), to look after Martin. Daphne is an eccentric, working class Englishwoman who professes to be "a bit psychic". Moreover, Martin brings his beloved Jack Russell Terrier, Eddie, whom Frasier despises. After some initial apprehension, Frasier grows very close to his new family.  In "IQ" (season six, episode 19), he is revealed to have been an Oxford University alumnus besides being a Harvard alumnus. In the same episode, he is said to have scored 129 in a school IQ test (his brother Niles scored 156).
Question: Are there any smaller characters that are important to the show?
Answer:
his beloved Jack Russell Terrier, Eddie, whom Frasier despises.
