Problem: Ralph Bakshi (born October 29, 1938) is an American director of animated and live-action films. In the 1970s, he established an alternative to mainstream animation through independent and adult-oriented productions. Between 1972 and 2015, he directed ten theatrically released feature films, six of which he wrote. He has been involved in numerous television projects as director, writer, producer and animator.

After production concluded on Harlem Nights, Bakshi wanted to distinguish himself artistically by producing a film in which live action and animated characters would interact. Bakshi said, "The illusion I attempted to create was that of a completely live-action film. Making it work almost drove us crazy." Hey Good Lookin' is set in Brooklyn during the 1950s; its lead characters are Vinnie, the leader of a gang named "The Stompers", his friend Crazy Shapiro and their girlfriends, Roz and Eva. Vinnie and Crazy Shapiro were based on Bakshi's high school friends Norman Darrer and Allen Schechterman. Warner Bros. optioned the screenplay and greenlit the film in 1973. An initial version of Hey Good Lookin' was completed in 1975. A three-minute promo of this version was screened at the 1975 Cannes Film Festival, and the film was scheduled for a Christmas 1975 release, but was moved to the summers of 1976 and later 1977, before ultimately being postponed indefinitely. Warner Bros. was concerned about any controversy the film would encounter as a result of the backlash over the film Coonskin, and felt that the film was "unreleasable" because of its mix of live action and animation, and it would not spend further money on the project. Bakshi financed the film's completion himself from the director's fees for other projects such as Wizards, The Lord of the Rings and American Pop. The live-action sequences of Hey Good Lookin' were gradually replaced by animation; among the eliminated live-action sequences was one featuring the glam punk band New York Dolls. Singer Dan Hicks worked on the initial musical score, but the final version was scored by John Madara. Hey Good Lookin' opened in New York City on October 1, 1982, and was released in Los Angeles in January 1983. The film's release was limited, and went largely unnoticed in the United States, although it garnered respectable business in foreign markets. In a brief review, Vincent Canby wrote that it was "not exactly incoherent, but whatever it originally had on its mind seems to have slipped away". Animation historian Jerry Beck wrote, "the beginning of the film is quite promising, with a garbage can discussing life on the streets with some garbage. This is an example of what Bakshi did best--using the medium of animation to comment on society. Unfortunately, he doesn't do it enough in this film. There is a wildly imaginative fantasy sequence during the climax, when the character named Crazy starts hallucinating during a rooftop shooting spree. This scene almost justifies the whole film. But otherwise, this is a rehash of ideas better explored in Coonskin, Heavy Traffic, and Fritz the Cat." The film has since gained a cult following through cable television and home video. Quentin Tarantino stated that he preferred Hey Good Lookin' to Martin Scorsese's Mean Streets.

Why did Bakshi call it his best work?

Question:
Wonder Girls (Hangul: weondeogeolseu) was a South Korean girl group formed by JYP Entertainment. The group's final line-up consisted of Yubin, Yeeun, Sunmi and Hyerim. Members Sunye and Sohee officially left the group in 2015, while Hyuna left in late 2007. They were co-managed in the United States by Creative Artists Agency.
After Park Jin-young revealed the name of his first girl group Wonder Girls in May 2006, the Wonder Girls were introduced through a TV show titled MTV Wonder Girls. The first four episodes outlined the characteristics and profiles of each member. Shortly after selecting Yeeun as the fifth member, the Wonder Girls held their first showcase in the MTV Studio. They performed a cover version of "Don't Cha" by the Pussycat Dolls as well as original songs, including "Irony" and "mianhan maeum" ("It's Not Love"). Sunye sang her version of Destiny's Child's "Stand Up for Love", while Hyuna performed a showcase of her dancing skills. The other three members--Yeeun, Sunmi and Sohee--performed a cover version of Janet Jackson's "Together Again". The Wonder Girls officially debuted in early 2007 on MBC's Show! Music Core, performing "Irony", the hip-hop single from their first album, The Wonder Begins. The album sold 11,454 physical copies in 2007. Shortly after, "Wonderfuls", the official Wonder Girls fanclub, was established. The group held several showcases in China after receiving Chinese lessons. In mid-2007, however, members of the Wonder Girls were beset by various injuries and health problems. On June 25, Sohee was sidelined for a month after tearing a knee ligament in a fall from a running motorcycle during the filming of her movie, ddeugeoun geosi joha (I Like It Hot). The remaining four members continued performing until late July, when Hyuna was withdrawn from the group by her parents due to their concern over her problems with chronic gastroenteritis and fainting spells. In autumn 2007, the talent agency Good Entertainment sent their trainee Yubin to JYP Entertainment as a replacement for Hyuna. She made her debut three days later in the group's live performance of "Tell Me" on Music Bank. Their first full-length album, The Wonder Years, was released the following week with "Tell Me" as the lead single. Due to the last-minute addition of Yubin, the album version does not contain her part. However, the performance version of the song was reworked to include a bridge with rapping by Yubin. The single was a hit and reached number one on various Korean television and internet music charts, including KBS's Music Bank. The song also became a number one hit in Thailand. The choreography for the song was simple and widely imitated: by October, many fan performances of the dance circulated on video sharing sites such as YouTube and Daum, including one by a group of policemen who were eventually profiled on SBS's Star King. The dance's popularity was immense and the explosive attention it received became widely known as the "Tell Me Virus", earning the group the title of "Nation's Little Sisters". The Wonder Girls had an extensive promotional schedule for their album, and in late 2007 they began performing their second single, "i babo" ("This Fool"). MTV also began broadcasting The Wonder Life, a reality TV series starring the girls.
