Mike Nichols: American Masters is a 2016 documentary film directed by Elaine May about the life of Mike Nichols broadcast on the PBS series "American Masters".
 It is derived from a lengthy interview with Nichols conducted by producer Julian Schlossberg.
 Brian Lowry of "Variety" has called it "the last memorable Nichols-May collaboration."
 Richard Brody said that although it is not a major contribution to May's life's work, it "is nonetheless distinctive in its sparseness, its fixed and almost obsessive concentration on Nichols’s face and voice... [it's] May’s highest tribute to Nichols."
Mike Nichols (born Mikhail Igor Peschkowsky; November 6, 1931 – November 19, 2014) was an American film and theatre director, producer, actor and comedian.
 He was noted for his ability to work across a range of genres and an aptitude for getting the best out of actors regardless of their acting experience.
 Nichols began his career in the 1950s with the comedy improvisational troupe, The Compass Players, predecessor of The Second City, in Chicago.
 He then teamed up with his improv partner, Elaine May, to form the comedy duo Nichols and May.
 Their live improv acts were a hit on Broadway resulting in three albums, with their debut album winning a Grammy Award.
The Doorway to Hell is a 1930 American Pre-Code crime film directed by Archie Mayo and starring Lew Ayres and James Cagney, in his second film role.
 The film was based on the story "A Handful of Clouds", written by Rowland Brown.
 The film's title was typical of the sensationalistic titles of many Pre-Code films.
 It was marketed with the tagline, "The picture Gangland defied Hollywood to make!"
Samuel Alexander "Sam" O'Steen (November 6, 1923 – October 11, 2000) was an American film editor and director.
 He had an extended, notable collaboration with the director Mike Nichols, with whom he edited twelve films between 1966 and 1994.
 Among the notable films that O'Steen edited were "Who's Afraid of Virginia Woolf" (directed by Mike Nichols, 1966), "Cool Hand Luke" (directed by Stuart Rosenberg, 1967), "The Graduate" (directed by Mike Nichols, 1967), "Rosemary's Baby" (directed by Roman Polanski, 1968), and "Chinatown" (directed by Roman Polanski, 1974).
 On a 2012 listing of the 75 best edited films of all time, compiled by the Motion Picture Editors Guild based on a survey of its members, both "The Graduate" and "Chinatown" appear.
American recording artist Kelly Rowland has embarked on eight concert tours during her career, six of which as a solo artist, including three of her own, two as a collaborative act and one as an opening act.
 In her six solo live tours and notable events dates, she has performed as a solo singer in over 119 shows in six continents through twenty-one countries: in Asia (China, Japan, Philippines, Vietnam, Malaysia, Singapore), in Africa (Nigeria), in Europe (Germany, United Kingdom, France, Italy, Netherlands, Belgium, Switzerland, Denmark, Monaco), in North America (United States, Canada and The Bahamas), in South America (Brazil) and in Oceania (Australia, and the US State of Hawaii).
 Throughout a career spanning 18 years, Rowland has sold over 40 million records as a solo artist with four studio albums, two compilation albums, one box set, two extended plays and forty-three singles, including nineteen as a featured artist and five promotional singles, and a further 60 million records with Destiny's Child.
 Her work has earned her several awards and nominations, including four Grammy Awards, a Billboard Music Award and a Soul Train Music Award.
 Rowland has also received a star on the Hollywood Walk of Fame with Destiny's Child, and as a solo artist she has been honored by the American Society of Composers, Authors and Publishers and "Essence" for her contributions to music.
 In 2014, Fuse ranked Rowland in their "100 Most Award-Winning Artists" list at number 20.
