Answer the question at the end by quoting:

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.
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.

How was Tropic Thunder promoted?

A trailer for the film was released in April 2008.

IN: Kulwicki grew up in Greenfield, Wisconsin, a suburb of Milwaukee known for its Polish-American neighborhoods, near the Milwaukee Mile racetrack. After his mother died, his family moved in with his grandmother, who died when Kulwicki was in seventh grade. A year later, his only brother died of a hemophilia-related illness. Kulwicki attended Pius XI High School, a Roman Catholic high school in Milwaukee, and received a bachelor of science degree in mechanical engineering from the University of Wisconsin-Milwaukee in 1977.

Kulwicki died in an airplane crash on Thursday April 1, 1993. He was returning from an appearance at the Knoxville Hooters in a Hooters corporate plane on a short flight across Tennessee before the Sunday spring race at Bristol. The plane slowed and crashed just before final approach at Tri-Cities Regional Airport near Blountville. The National Transportation Safety Board attributed the crash to the pilot's failure to use the airplane's anti-ice system to clear ice from the engine inlet system.  Kulwicki was buried at St. Adalbert's Cemetery in Milwaukee; the funeral was attended by NASCAR President Bill France, Jr. and numerous drivers. Kulwicki's racecar transporter was driven from the rainy track later that Friday morning while other teams and the media watched it travel slowly around the track with a black wreath on its grille. In 2008, Kyle Petty described the slow laps as "the saddest thing I've ever seen at a racetrack... We just sat and cried." Kulwicki had competed in five NASCAR races that season with two Top 5 finishes, and was ranked ninth in points at his death. In his career, he had won five NASCAR Winston Cup races, 24 pole positions, 75 Top 10 finishes, and one championship in 207 races.  His car was driven by road course specialist Tommy Kendall on road courses and by Jimmy Hensley at the other tracks. It was raced for most of the 1993 season until the team was sold to Geoff Bodine, who operated it as Geoff Bodine Racing.  Kulwicki had been selected to compete in the 1993 International Race of Champions (IROC) series as the reigning Winston Cup champion. He competed in two IROC races before his death, finishing ninth at Daytona and eleventh at Darlington. Dale Earnhardt raced for Kulwicki in the final two IROC races, and the prize money for those races and their fifth place combined points finish was given to the Winston Cup Racing Wives Auxiliary, Brenner Children's Hospital and St. Thomas Aquinas Church charities.
