Problem: Background: Mark Romanek (born September 18, 1959) is an American filmmaker whose directing work includes feature films, television, music videos and commercials. Romanek wrote and directed the 2002 film One Hour Photo and directed the 2010 film Never Let Me Go. His most notable music videos include "Hurt" (Johnny Cash), "Closer" (Nine Inch Nails), "Can't Stop" (Red Hot Chili Peppers), "Bedtime Story" (Madonna), "Scream" (Michael & Janet Jackson), and "Shake It Off" (Taylor Swift).
Context: In 2002, Romanek wrote and directed his second feature film, One Hour Photo, about a department store photo processor who becomes obsessed with a family through their snapshots. The film proved to be only a moderate hit, but still established Romanek as a respected film director. Rumors spread that the studio, Fox Searchlight, had forced changes on Romanek that seriously altered the film from how he had intended it. He has dismissed this story, however, stating that there never was a "director's cut" of One Hour Photo and that the studio did not exercise any editorial control. In 2005, Romanek was scheduled to direct a film adaptation of the book A Cold Case, but the project languished in development hell. In December 2005, it was announced that he would direct A Million Little Pieces, the film adaptation of the book of the same name, but due to events regarding the authenticity of the book's content, it has also become a subject of speculation as to whether the film will indeed be made or not. On February 8, 2007, he signed on to direct The Wolfman, but dropped out. He also signed on to direct The Strangers, but also dropped out due to not receiving a bigger budget. Romanek's third feature was the 2010 British dystopian drama Never Let Me Go. In October 2011, he was planning on taking over from director Ron Howard on the film adaptation of Dan Brown's bestselling novel The Lost Symbol. However, the film was eventually scrapped in favor of making Brown's fourth novel, Inferno, into a feature film instead.
Question: what is a feature film he did?
Answer: In 2002, Romanek wrote and directed his second feature film, One Hour Photo, about a department store photo processor who becomes obsessed with a family through their snapshots.

Problem: Background: David Michael Letterman (born April 12, 1947) is an American television host, comedian, writer, and producer. He hosted a late night television talk show for 33 years, beginning with the February 1, 1982, debut of Late Night with David Letterman on NBC, and ending with the May 20, 2015, broadcast of Late Show with David Letterman on CBS. In total, Letterman hosted 6,028 episodes of Late Night and Late Show, surpassing friend and mentor Johnny Carson as the longest-serving late night talk show host in American television history. In 1996 Letterman was ranked 45th on TV Guide's 50 Greatest TV Stars of All Time.
Context: NBC kept Letterman under contract to try him in a different time slot. Late Night with David Letterman debuted February 1, 1982; the first guest on the first show was Bill Murray. Murray later went on to become one of Letterman's most recurrent guests, guesting on the show's 30th anniversary episode, which aired January 31, 2012 and on the very last show, which aired May 20, 2015. The show ran Monday through Thursday at 12:30 a.m. Eastern Time, immediately following The Tonight Show Starring Johnny Carson (a Friday night broadcast was added in June 1987). It was seen as being edgy and unpredictable, and soon developed a cult following (particularly among college students). Letterman's reputation as an acerbic interviewer was borne out in verbal sparring matches with Cher (who even called him an asshole on the show), Shirley MacLaine, Charles Grodin, and Madonna. The show also featured comedy segments and running characters, in a style heavily influenced by the 1950s and 1960s programs of Steve Allen. The show often featured quirky, genre-mocking regular features, including "Stupid Pet Tricks" (which had its origins on Letterman's morning show), Stupid Human Tricks, dropping various objects off the roof of a five-story building, demonstrations of unorthodox clothing (such as suits made of Alka-Seltzer, Velcro and suet), a recurring Top 10 list, the Monkey-Cam (and the Audience Cam), a facetious letter-answering segment, several "Film[s] by My Dog Bob" in which a camera was mounted on Letterman's own dog (often with comic results) and Small Town News, all of which would eventually move with Letterman to CBS. Other memorable moments included Letterman using a bullhorn to interrupt a live interview on The Today Show, announcing that he was the NBC News president and that he was not wearing any pants; walking across the hall to Studio 6B, at the time the news studio for WNBC-TV, and interrupting Al Roker's weather segments during Live at Five; and staging "elevator races", complete with commentary by NBC Sports' Bob Costas. In one infamous appearance, in 1982, Andy Kaufman (who was already wearing a neck brace) appeared with professional wrestler Jerry Lawler, who slapped and knocked the comedian to the ground (though Lawler and Kaufman's friend Bob Zmuda later revealed that the event was staged).
