Paul Thomas Anderson filmography: American director, screenwriter, and producer Paul Thomas Anderson has directed seven feature-length films, five short films, twelve music videos, one documentary, one television episode as a guest segment director, and one theatrical play.  He made his directorial debut with the mockumentary short film "The Dirk Diggler Story" (1988), at the age of 18, about a pornographic actor in the 1970s.  Anderson followed it five years later with another short film, "Cigarettes & Coffee" in 1993.  In 1996, Anderson wrote and directed the neo-noir crime thriller "Hard Eight", starring Philip Baker Hall, John C. Reilly, Gwyneth Paltrow, and Samuel L. Jackson.  The film was well received, with film critic Roger Ebert saying of it in his review, "Movies like "Hard Eight" remind me of what original, compelling characters the movies can sometimes give us."  Using the basis of "The Dirk Diggler Story", Anderson wrote and directed an expansion of the film entitled "Boogie Nights" in 1997.  The film starred Mark Wahlberg as Eddie Adams/"Dirk Diggler" during the Golden Age of Porn in the 1970s and his eventual downfall in the 1980s.  "Boogie Nights" received acclaim from critics and was a commercial success; at the 70th Academy Awards ceremony, the film was nominated for three Academy Awards, including for Best Supporting Actor (Burt Reynolds), Best Supporting Actress (Julianne Moore) and Best Original Screenplay.

List of Best Supporting Actor winners by age: This is a list of winners of the Academy Award of Merit for Performance by an Actor in a Supporting Role, presented annually by the Academy of Motion Picture Arts and Sciences (AMPAS) to an actor who has delivered an outstanding performance while working within the film industry.  More popularly known as the Academy Award (or the Oscar) for Best Supporting Actor, this award was initially presented at the 9th Academy Awards ceremony for 1936 and was most recently presented at the 88th Academy Awards ceremony for 2015.  Throughout the past 80 years, accounting for ties and repeat winners, AMPAS has presented a total of 81 Best Supporting Actor awards to 73 different actors.  This list is current as of the 89th Academy Awards ceremony held on February 26, 2017.

Academy Honorary Award: The Academy Honorary Award – instituted in 1948 for the 21st Academy Awards (previously called the Special Award, which was first presented in early 1929) – is given annually by the Board of Governors of the Academy of Motion Picture Arts and Sciences (AMPAS) to celebrate motion picture achievements that are not covered by existing Academy Awards, although prior winners of competitive Academy Awards are not excluded from receiving the Honorary Award.  Unless otherwise specified, Honorary Award recipients receive the same gold Oscar statuettes received by winners of the competitive Academy Awards.  Unlike the Special Achievement Award instituted in 1972 (and discontinued in 1995), those on whom the Academy confers its Honorary Award do not have to meet "the Academy's eligibility year and deadline requirements."  Like the Special Achievement Award, the Special Award and Honorary Award have been used to reward significant achievements of the year that did not fit in existing categories, subsequently leading the Academy to establish several new categories, and to honor exceptional career achievements, contributions to the motion picture industry, and service to the Academy.  The Academy Honorary Award is often awarded in preference to those with noted achievements in motion pictures who have nevertheless never won an Academy Award.  Thus, many of its recipients are Classic Hollywood stars, such as Lillian Gish, Barbara Stanwyck, Kirk Douglas, and Lauren Bacall.
