Problem: Background: Robert Dennis Crumb (; born August 30, 1943) is an American cartoonist and musician who often signs his work R. Crumb. His work displays a nostalgia for American folk culture of the late 19th and early 20th centuries, and satire of contemporary American culture. Crumb is a prolific artist and contributed to many of the seminal works of the underground comix movement in the 1960s, including being a founder of the first successful underground comix publication, Zap Comix, contributing to all 16 issues. He was additionally contributing to the East Village Other and many other publications, including a variety of one-off and anthology comics.
Context: In January 1967 Crumb came across two friends in a bar who were about to leave for San Francisco; Crumb was interested in the work of San Francisco-based psychedelic poster artists, and on a whim asked if he could join them. There, he contributed upbeat LSD-inspired countercultural work to underground newspapers. The work was popular, and Crumb was flooded with requests, including to illustrate a full issue of Philadelphia's Yarrowstalks. Independent publisher Don Donahue invited Crumb to make a comic book; Crumb drew up two issues of Zap Comix, and Donahue published the first in February 1968 under the publisher name Apex Novelties. Crumb had difficulty at first finding retailers who would stock it, and at first his wife took to selling the first run herself out of a baby carriage. Crumb met cartoonist S. Clay Wilson, an art school graduate who saw himself as a rebel against middle-class American values and whose comics were violent and grotesque. Wilson's attitude inspired Crumb to give up the idea of the cartoonist-as-entertainer and to focus on comics as open, uncensored self-expression; in particular, his work soon became sexually explicit, as in the pornographic Snatch he and Wilson produced late in 1968. The second issue of Zap appeared in June with contributions from Wilson and poster artists Victor Moscoso and Rick Griffin. In December, Donahue published the still-unreleased issue as #0 and a new third issue with Gilbert Shelton joining the roster of regulars. Zap was financially successful, and developed a market for underground comix. Crumb was a prolific cartoonist in the late 1960s and early 1970s; at his peak point of output he produced 320 pages over two years. He produced much of his best-known work then, including his Keep on Truckin' strip, and strips featuring characters such as the bohemian Fritz the Cat, spiritual guru Mr. Natural, and oversexed African-American stereotype Angelfood McSpade. During this period, he launched a series of solo titles, including Despair, Uneeda (both published by Print Mint in 1969), Big Ass Comics, R. Crumb's Comics and Stories, Motor City Comics (all published by Rip Off Press in 1969), Home Grown Funnies (Kitchen Sink Press, 1971) and Hytone Comix (Apex Novelties, 1971), in addition to founding the pornographic anthologies Jiz and Snatch (both Apex Novelties, 1969).
Question: Was this successful?

Problem: Background: Ford was born at the Swedish Covenant Hospital in Chicago, Illinois to Christopher Ford (born John William Ford), an advertising executive and former actor, and Dorothy (nee Nidelman), a former radio actress. His father is Irish and his mother is Jewish. A younger brother, Terence, was born in 1945. Ford's paternal grandparents, John Fitzgerald Ford and Florence Veronica Niehaus, were of Irish Catholic and German descent, respectively.
Context: In 1964, after a season of summer stock with the Belfry Players in Wisconsin, Ford traveled to Los Angeles to apply for a job in radio voice-overs. He did not get it, but stayed in California and eventually signed a $150-a-week contract with Columbia Pictures' New Talent program, playing bit roles in films. His first known role was an uncredited one as a bellhop in Dead Heat on a Merry-Go-Round (1966). There is little record of his non-speaking roles (or "extra" work) in film. Ford was at the bottom of the hiring list, having offended producer Jerry Tokovsky after he played a bellboy in the feature. He was told by Tokovsky that when actor Tony Curtis delivered a bag of groceries, he did it like a movie star; Ford felt his job was to act like a bellboy. Ford managed to secure other roles in movies, such as A Time for Killing (The Long Ride Home), starring Glenn Ford; George Hamilton; and Inger Stevens. His speaking roles continued next with Luv (1967), though he was still uncredited. He was finally credited as "Harrison J. Ford" in the 1967 Western film A Time for Killing, but the "J" did not stand for anything, since he has no middle name. It was added to avoid confusion with a silent film actor named Harrison Ford, who appeared in more than 80 films between 1915 and 1932 and died in 1957. Ford later said that he was unaware of the existence of the earlier actor until he came upon a star with his own name on the Hollywood Walk of Fame. Ford soon dropped the "J" and worked for Universal Studios, playing minor roles in many television series throughout the late 1960s and early 1970s, including Gunsmoke, Ironside, The Virginian, The F.B.I., Love, American Style, and Kung Fu. He appeared in the western Journey to Shiloh (1968) and had an uncredited, non-speaking role in Michelangelo Antonioni's 1970 film Zabriskie Point as an arrested student protester. Not happy with the roles being offered to him, Ford became a self-taught professional carpenter to support his then-wife and two young sons. Casting director and fledgling producer Fred Roos championed the young Ford and secured him an audition with George Lucas for the role of Bob Falfa, which Ford went on to play in American Graffiti (1973). Ford's relationship with Lucas would profoundly affect his career later on. After director Francis Ford Coppola's film The Godfather was a success, he hired Ford to expand his office and gave him small roles in his next two films, The Conversation (1974) and Apocalypse Now (1979); in the latter film he played an army officer named "G. Lucas".
Question: Did he play any other roles
Answer:
small roles in his next two films, The Conversation (1974) and Apocalypse Now (1979);
