Background: Joaquin Rafael Phoenix (; ne Bottom; born October 28, 1974) is an American actor, producer, and activist. For his work as an actor, Phoenix has received a Grammy Award, a Golden Globe Award, and has three Academy Award and British Academy Film Award nominations. Phoenix started acting in television shows with his brother River Phoenix and sister Summer Phoenix.
Context: In 2006, Phoenix was invited to join the Academy of Motion Picture Arts and Sciences.  In 2007, Phoenix reunited with director James Gray for the film We Own the Night, which he also produced. In the film, Phoenix played a New York nightclub manager who tries to save his brother and father from Russian mafia hit men. The film premiered at the 2007 Cannes Film Festival, receiving mixed reviews from critics and grossed a total of $54.5 million worldwide. Critic Peter Travers described Phoenix as "electrifying and then some", and he was awarded the People's Choice Award for Favorite Leading Man for the performance. For his second film of 2007, Phoenix also reunited with director Terry George for the film Reservation Road. In it, Phoenix played a father obsessed with finding out who killed his son in a hit-and-run accident. The film failed at the box office  and received negative reviews from critics, with film critic Peter Travers writing "Even the best actors -- and I'd rank Joaquin Phoenix and Mark Ruffalo among their generation's finest -- can't save a movie that aims for tragedy but stalls at soap opera."  Phoenix made his third collaboration with director James Gray in the film Two Lovers (2008), where he played a bachelor torn between the family friend his parents wish he would marry and his beautiful but volatile new neighbor. Two Lovers premiered in competition at the 2008 Cannes Film Festival in May, receiving largely positive reviews, especially Phoenix who was praised by film critics David Edelstein who wrote "He [Phoenix] is, once again, stupendous, and stupendous in a way he has never been before" and Roger Ebert describing his performance as "perfect pitch". Two Lovers grossed $16 million worldwide.  Phoenix's mockumentary film I'm Still Here (2010) premiered at the 67th Venice International Film Festival on September 6, 2010. The film was directed by Phoenix's then brother-in-law Casey Affleck and was also written by Affleck and Phoenix himself. The film purports to follow the life of Phoenix, from the announcement of his retirement from acting, through his transition into a career as a hip hop artist. Filming officially began on January 16, 2009 at a Las Vegas nightclub. Throughout the filming period, Phoenix remained in character for public appearances, giving many the impression that he was genuinely pursuing a new career. Although widely suspected to be a "mockumentary," the fact that the events of the film had been deliberately staged was not disclosed until after the film had been released. The film received mixed reviews and failed at the box office. After the releasing of the film, Phoenix took a self-imposed break from acting.

Background: Art Spiegelman (; born Itzhak Avraham ben Zeev on February 15, 1948) is an American cartoonist, editor, and comics advocate best known for his graphic novel Maus. His work as co-editor on the comics magazines Arcade and Raw has been influential, and from 1992 he spent a decade as contributing artist for The New Yorker, where he made several high-profile and sometimes controversial covers. He is married to designer and editor
Context: Hired by Tina Brown as a contributing artist in 1992, Spiegelman worked for The New Yorker for ten years. Spiegelman's first cover appeared on the February 15, 1993, Valentine's Day issue and showed a black West Indian woman and a Hasidic man kissing. The cover caused turmoil at The New Yorker offices. Spiegelman intended it to reference the Crown Heights riot of 1991 in which racial tensions led to the murder of a Jewish yeshiva student. Spiegelman had twenty-one New Yorker covers published, and submitted a number which were rejected for being too outrageous.  Within The New Yorker's pages, Spiegelman contributed strips such as a collaboration titled "In the Dumps" with children's illustrator Maurice Sendak and an obituary to Charles M. Schulz titled "Abstract Thought is a Warm Puppy". An essay he had published there on Jack Cole, the creator of Plastic Man, called "Forms Stretched to their Limits" was to form the basis for a book in 2001 about Cole called Jack Cole and Plastic Man: Forms Stretched to their Limits.  The same year, Voyager Company published a CD-ROM version of Maus with extensive supplementary material called The Complete Maus, and Spiegelman illustrated a 1923 poem by Joseph Moncure March called The Wild Party. Spiegelman contributed the essay "Getting in Touch With My Inner Racist" in the September 1, 1997 issue of Mother Jones.  Spiegelman's influence and connections in New York cartooning circles drew the ire of political cartoonist Ted Rall in 1999. In an article titled "The King of Comix" in The Village Voice, Rall accused Spiegelman of the power to "make or break" a cartoonist's career in New York, while denigrating Spiegelman as "a guy with one great book in him". Cartoonist Danny Hellman responded by sending a forged email under Rall's name to thirty professionals; the prank escalated until Rall launched a defamation suit against Hellman for $1.5 million. Hellman published a "Legal Action Comics" benefit book to cover his legal costs, to which Spiegelman contributed a back-cover cartoon in which he relieves himself on a Rall-shaped urinal.  In 1997, Spiegelman had his first children's book published: Open Me... I'm a Dog, with a narrator who tries to convince its readers that it is a dog via pop-ups and an attached leash. From 2000 to 2003 Spiegelman and Mouly edited three issues of the children's comics anthology Little Lit, with contributions from Raw alumni and children's book authors and illustrators.
