Background: Tropic Thunder is a 2008 black satirical action comedy film directed by Ben Stiller, who stars with Jack Black and Robert Downey Jr. as a group of prima donna actors who are making a fictional Vietnam War film. When their frustrated director drops them in the middle of a jungle, they are forced to rely on their acting skills to survive the real action and danger. The screenplay by Justin Theroux, Stiller, and Etan Cohen was from a story by Stiller and Theroux. The film was produced by Stuart Cornfeld, Stiller and Eric McLeod for Red Hour Productions and DreamWorks Pictures as an international co-production between the United States, Germany, and the United Kingdom.
Context: A trailer for the film was released in April 2008. The Calgary Herald gave it a rating of 3/5, commenting: "This could either be good or very, very bad." Gary Susman of Entertainment Weekly questioned whether the film would "... turn into precisely the kind of bloated action monstrosity that it's making fun of." The trailer received the "Best Comedy Trailer" award at the 9th annual Golden Trailer Awards. DreamWorks also released a red band trailer, the first of its kind used by the studio to promote one of its films. Stiller, Downey, and Black appeared on the seventh-season finale of American Idol in a sketch as The Pips performing with Gladys Knight (via archival footage). The three actors also later performed a sketch at the 2008 MTV Movie Awards which featured the actors attempting to create a successful viral video to promote the film with awkward results. In September 2008, Stiller and Downey attended the San Sebastian International Film Festival to promote the film. A screening was shown, but it was not chosen to compete against the other films at the festival. Between April 2008 and the film's commercial release in August 2008, the film had over 250 promotional screenings. On August 3, 2008, Stiller, Downey, and Black visited Camp Pendleton, a U.S. Marine Corps base in California, to present a screening to over a thousand military members and their families. The screening was on behalf of the United Service Organizations and included the actors heading to the screening by helicopter and Humvees. On August 8, 2008, a special 30-minute fictional E! True Hollywood Story aired about the making of Tropic Thunder. In video games, a themed scavenger hunt was incorporated into Tom Clancy's Rainbow Six: Vegas 2, and Stiller allowed his likeness to be used in the online Facebook application game based on the film. As a tie-in for the film's release, Paramount announced it would market the energy drink known in the film as "Booty Sweat". Michael Corcoran, Paramount's president of consumer products, commented on the release: "We're very excited, because it has the potential to live for quite a while, well beyond the film." The drink was sold in college bookstores, on Amazon.com, and at other retailers.
Question: Who is the director of the film?
Answer:

Problem: Background: Motion City Soundtrack was an American rock band that formed in Minneapolis, Minnesota in 1997. The band's line-up consisted of vocalist and guitarist Justin Pierre, lead guitarist Joshua Cain, keyboardist Jesse Johnson, bassist Matthew Taylor, and drummer Tony Thaxton.
Context: Motion City Soundtrack was formed in Minneapolis, Minnesota in 1997 by singer-songwriter Justin Pierre and guitarist Joshua Cain. Previously, the duo had separately played in a number of bands. Cain was in a group named the Saddest Girl Story, and recruited Pierre to join as a singer. He was subsequently in a band called Boxcar, and following its dissolution, he and Pierre founded Motion City Soundtrack together. The band's name was created by Cain's brother, Brian. Their early days were difficult, as they found it hard to break out of their local scene. When they could get weeks off from their jobs, they would tour. According to Cain, the members of the band soon realized that there "wasn't really anywhere to play [shows] in Minneapolis", and that they would have to "tour all the time" to rise in popularity. In its early years, the group went through several lineup changes. Through these, Cain and Pierre would often have to take over keyboard duties during shows. The group's first release was a 7" single, "Promenade / Carolina", released in 1999. Their next two releases, both extended plays--Kids for America and Back to the Beat--were released the following year. Over the course of the early 2000s, the band continued to tour and shuffle through members. In late 2001, while touring in Milton, Pennsylvania with the band Submerge, they convinced two of its members--bassist Matthew Taylor and drummer Tony Thaxton--to join Motion City. Thaxton initially took about a year to convince to join the band. Jesse Johnson, a friend and co-worker of Cain's, joined the band as keyboardist just three weeks before the band recorded their first album. Johnson had never played the keyboard before but Cain taught him the parts that had already been written. After their first attempt at self-recording an album failed, the band culled together $6,000 to record with producer Ed Rose, best known for his work with the Get Up Kids. They recorded much of their debut album, I Am the Movie, in ten days. Initial copies were hand-packaged inside floppy disks, which were sold out of the back of their tour van for a year. The band began receiving offers from various record labels, including Universal, Triple Crown Records, and Drive-Thru Records, and they performed at industry showcases. Meanwhile, Brett Gurewitz, founder of Epitaph Records, learned of the band from members of the group Matchbook Romance. He attended four of their shows in Los Angeles that Pierre later regarded as among his worst, as his voice was poor from constant touring. While they were interested in Universal, they chose to sign to Epitaph as they felt the contract was less restrictive and more honest. Eli Janney from Girls Against Boys helped the band secure management and a lawyer. Motion City became part of a slew of Epitaph signings, including Matchbook Romance, Scatter the Ashes and From First to Last, amid concerns the Southern California label had strayed too far from its roots, and seemed "a little too emo."
