Background: The Blues Brothers is a 1980 American musical comedy film directed by John Landis. It stars John Belushi and Dan Aykroyd as "Joliet" Jake and Elwood Blues, characters developed from "The Blues Brothers" musical sketch on the NBC variety series Saturday Night Live. The film's screenplay was written by Aykroyd and Landis. It features musical numbers by rhythm and blues (R&B), soul, and blues singers James Brown, Cab Calloway, Aretha Franklin, Ray Charles, and John Lee Hooker.
Context: Much of the film was shot on location in and around Chicago between July and October 1979, including Wauconda, Illinois, where the car crashes into the side of Route 12. Made with the cooperation of Mayor Jane M. Byrne, it is credited for putting Chicago on the map as a venue for filmmaking. Nearly 200 movies have been filmed in Chicago. "Chicago is one of the stars of the movie. We wrote it as a tribute," Dan Aykroyd told the Chicago Sun-Times in an article written to mark the film's 25th-anniversary DVD release.  The first traffic stop was in Park Ridge, Illinois. The shopping mall car chase was filmed in the real, albeit shuttered, Dixie Square Mall, in Harvey, Illinois. The bridge jump was filmed on an actual drawbridge, the 95th Street bridge over the Calumet River, on the southeast side of Chicago. The main entrance to Wrigley Field (and its sign reading "Save lives. Drive safely, prevent fires.") makes a brief appearance when the "Illinois Nazis" visit it after Elwood falsely registers the ballpark's location, 1060 West Addison, as his home address on his driver's license. (Elwood's Illinois driver's license number is an almost-valid encoded number, with Dan Aykroyd's own birth date embedded.) Jake's final confrontation with his girlfriend was filmed in a replica of a section of the abandoned Chicago freight tunnel system. The other chase scenes included lower Wacker Drive, Lake Street, and Richard J. Daley Center.  In the final car chase scene, the production actually dropped a Ford Pinto, representing the one driven by the "Illinois Nazis", from a helicopter at an altitude of about 1,200 feet--and had to gain a Special Airworthiness Certificate from the Federal Aviation Administration to do it. The FAA was concerned that the car could prove too aerodynamic in a high-altitude drop, and pose a threat to nearby buildings. The shot leading up to the car drop, where the "Illinois Nazis" drive off a freeway ramp, was shot in Milwaukee, Wisconsin, near the Hoan Bridge on Interstate 794. The Lake Freeway (North) was a planned but not completed six-lane freeway, and I-794 contained an unfinished ramp off which the Nazis drove. Several Milwaukee skyscrapers are visible in the background as the Bluesmobile flips over, notably the U.S. Bank Center.  The Palace Hotel Ballroom, where the band performs its climactic concert, was at the time of filming a country club, but later became the South Shore Cultural Center, named after the Chicago neighborhood where it is located. The interior concert scenes were filmed in the Hollywood Palladium.  The filming in downtown Chicago was conducted on Sundays during the summer of 1979, and much of the downtown was cordoned off from the public. Costs for filming the largest scene in the city's history totaled $3.5 million. Permission was given after Belushi and Aykroyd offered to donate $50,000 to charity after filming. Although the Bluesmobile was allowed to be driven through the Daley Center lobby, special breakaway panes were temporarily substituted for the normal glass in the building. The speeding car caused $7,650 in damage to 35 granite paver stones and a bronze air grill in the building. Interior shots of the elevator, staircase, and assessor's office were all recreated in a film set for filming.
Question: who was the director?
Answer: 

Background: Albert Sidney Johnston (February 2, 1803 - April 6, 1862) served as a general in three different armies: the Texian (i.e. Republic of Texas) Army, the United States Army, and the Confederate States Army. He saw extensive combat during his 34-year military career, fighting actions in the Black Hawk War, Texas War of Independence, the Mexican-American War, the Utah War, and the American Civil War. Considered by Confederate States President Jefferson Davis to be the finest general officer in the Confederacy before the later emergence of Robert E. Lee, he was killed early in the Civil War at the Battle of Shiloh on April 6, 1862.
Context: At the outbreak of the American Civil War, Johnston was the commander of the U.S. Army Department of the Pacific in California. Like many regular army officers from the South, he was opposed to secession. But he resigned his commission soon after he heard of the secession of his adopted state of Texas. It was accepted by the War Department on May 6, 1861, effective May 3. On April 28 he moved to Los Angeles, the home of his wife's brother John Griffin. Considering staying in California with his wife and five children, Johnston remained there until May.  Soon, under suspicion by local Union officials, he evaded arrest and joined the Los Angeles Mounted Rifles as a private, leaving Warner's Ranch May 27. He participated in their trek across the southwestern deserts to Texas, crossing the Colorado River into the Confederate Territory of Arizona on July 4, 1861.  Early in the Civil War, Confederate President Jefferson Davis decided that the Confederacy would attempt to hold as much of its territory as possible, and therefore distributed military forces around its borders and coasts. In the summer of 1861, Davis appointed several generals to defend Confederate lines from the Mississippi River east to the Allegheny Mountains.  The most sensitive, and in many ways the most crucial areas, along the Mississippi River and in western Tennessee along the Tennessee and the Cumberland rivers were placed under the command of Maj. Gen. Leonidas Polk and Brig. Gen. Gideon J. Pillow. The latter had initially been in command in Tennessee as that State's top general. Their impolitic occupation of Columbus, Kentucky, on September 3, 1861, two days before Johnston arrived in the Confederacy's capital of Richmond, Virginia, after his cross-country journey, drove Kentucky from its stated neutrality. The majority of Kentuckians allied with the Union camp. Polk and Pillow's action gave Union Brig. Gen. Ulysses S. Grant an excuse to take control of the strategically located town of Paducah, Kentucky, without raising the ire of most Kentuckians and the pro-Union majority in the State legislature.
Question: what side was he on?
