Problem: Background: Joseph Frank "Buster" Keaton (October 4, 1895 - February 1, 1966) was an American actor, comedian, film director, producer, screenwriter, and stunt performer. He was best known for his silent films, in which his trademark was physical comedy with a consistently stoic, deadpan expression, earning him the nickname "The Great Stone Face". Critic Roger Ebert wrote of Keaton's "extraordinary period from 1920 to 1929, [when] he worked without interruption on a series of films that make him, arguably, the greatest actor-director in the history of the movies". His career declined afterward with a dispiriting loss of his artistic independence when he was hired by Metro-Goldwyn-Mayer and he descended into alcoholism, ruining his family life.
Context: Keaton's personal life had stabilized with his 1940 marriage, and now he was taking life a little easier, abandoning Columbia for the less strenuous field of feature films. Throughout the 1940s, Keaton played character roles in both "A" and "B" features. He made his last starring feature El Moderno Barba Azul (1946) in Mexico; the film was a low budget production, and it may not have been seen in the United States until its release on VHS in the 1980s, under the title Boom in the Moon. Critics rediscovered Keaton in 1949 and producers occasionally hired him for bigger "prestige" pictures. He had cameos in such films as In the Good Old Summertime (1949), Sunset Boulevard (1950), and Around the World in 80 Days (1956). In In The Good Old Summertime, Keaton personally directed the stars Judy Garland and Van Johnson in their first scene together where they bump into each other on the street. Keaton invented comedy bits where Johnson keeps trying to apologize to a seething Garland, but winds up messing up her hairdo and tearing her dress. Keaton also had a cameo as Jimmy, appearing near the end of the film It's a Mad, Mad, Mad, Mad World (1963). Jimmy assists Spencer Tracy's character, Captain C. G. Culpepper, by readying Culpepper's ultimately-unused boat for his abortive escape. (The restored version of that film, released in 2013, contains a restored scene where Jimmy and Culpeper talk on the telephone. Lost after the comedy epic's "roadshow" exhibition, the audio of that scene was discovered, and combined with still pictures to recreate the scene.) Keaton was given more screen time in A Funny Thing Happened on the Way to the Forum (1966). The appearance, since it was released after his death, was his posthumous swansong. Keaton also appeared in a comedy routine about two inept stage musicians in Charlie Chaplin's Limelight (1952), recalling the vaudeville of The Playhouse. With the exception of Seeing Stars, a minor publicity film produced in 1922, Limelight was the only time in which the two would ever appear together on film. In 1949, comedian Ed Wynn invited Keaton to appear on his CBS Television comedy-variety show, The Ed Wynn Show, which was televised live on the West Coast. Kinescopes were made for distribution of the programs to other parts of the country since there was no transcontinental coaxial cable until September 1951.

Background: Dame Helen Lydia Mirren, (nee Mironoff; born 26 July 1945) is an English actor. Mirren began her acting career with the Royal Shakespeare Company in 1967, and is one of the few performers who have achieved the Triple Crown of Acting. She won the Academy Award for Best Actress in 2007 for her performance as Queen Elizabeth II in The Queen and received the Olivier Award for Best Actress and Tony Award for Best Actress in a Play for the same role in The Audience. Mirren's other Academy Award nominations include The Madness of King George (1994), Gosford Park (2001) and The Last Station (2009).
Context: Mirren's first film of the 2000s was Joel Hershman's Greenfingers (2000), a comedy based on the true story about the award-winning prisoners of HMP Leyhill, a minimum-security prison. Mirren portrayed a devoted plantswoman in the film, who coaches a team of prison gardeners, led by Clive Owen, to victory at a prestigious flower show. The project garnered largely lukewarm reviews from critics, who felt that it added "nothing new to this already saturated genre" of British feel-good films. The same year, she began work on the mystery film The Pledge, actor Sean Penn's second directorial effort, in which she played a child psychologist. A critical success, the ensemble film tanked at the box office. Also the year, she filmed the American-Icelandic satirical drama No Such Thing opposite Sarah Polley. Directed by Hal Hartley, Mirren portrayed a soulless television producer in the film, who strives for sensationalistic stories. It was largely panned by critics. Her biggest critical and commercial success, released in 2001, became Robert Altman's all-star ensemble mystery film Gosford Park. An homage to writer Agatha Christie's whodunit style, the story follows a party of wealthy Britons and an American, and their servants, who gather for a shooting weekend at an English country house, resulting in an unexpected murder. Widely acclaimed by critics, it received multiple awards and nominations, including a second Academy Award nomination and first Screen Actors Guild Award win for Mirren's portrayal of the sternly devoted head servant Mrs. Wilson. Mirren's last film that year was Fred Schepisi's dramedy film Last Orders opposite Michael Caine and Bob Hoskins. In 2003, Mirren starred in Nigel Cole's comedy Calendar Girls, inspired by the true story of a group of Yorkshire women who produced a nude calendar to raise money for Leukaemia Research under the auspices of the Women's Institutes. Mirren was initially resistant to join the project, at first dismissing it as another middling British picture, but rethought her decision upon learning of the casting of co-star Julie Walters. The film garnered generally positive reactions by film critics, and grossed $96,000,000 worldwide. In addition, the picture earned Satellite, Golden Globe, and European Film Award nominations for Mirren. Her other film that year was the Showtime television film The Roman Spring of Mrs. Stone opposite Olivier Martinez, and Anne Bancroft, based on the 1950 novel of the same title by Tennessee Williams.
