Problem: 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: Were promos popular?
Answer: In September 2008, Stiller and Downey attended the San Sebastian International Film Festival to promote the film.

Problem: Background: Corey Todd Taylor (born December 8, 1973) is an American musician, singer, songwriter, actor, and author, best known as the lead singer and lyricist of the bands Slipknot and Stone Sour. Taylor formed Stone Sour in 1992, playing in the Des Moines area, and working on a demo. He joined Slipknot in 1997 to replace their original vocalist and has subsequently released five studio albums with them. After the first two Slipknot albums went Platinum, Taylor revived Stone Sour to record an album and tour in 2002.
Context: In Des Moines, Iowa, Joey Jordison, Shawn Crahan, and Mick Thomson approached him asking him to join Slipknot. He agreed to go to one of their practices, and ended up singing in front of them. Of Slipknot's nine members, Corey was the sixth to join the band. Performing with Slipknot, he would also come to be known as "Number Eight", being that the band follows a numbering scheme for its members, ranging from 0-8. According to Shawn Crahan, Corey wanted number eight, because it symbolizes infinity.  Feeling he could expand more inside Slipknot than in Stone Sour, Taylor temporarily quit Stone Sour, even though they were recording an album with Sean McMahon. Taylor's first gig with Slipknot was on August 22, 1997, which according to band members did not go well. During his first gig, Taylor did not perform wearing a mask; however, for his second show nearly a month later, Corey wore a mask that resembles his debut album mask. Taylor's current mask was described by MTV's Chris Harris as looking "as though it were made of dried, human flesh--like Leatherface, if only he used moisturizer."  Taylor has recorded with Slipknot since the release of their second demo album, a self-titled demo used to promote the band to prospective labels and producers. As permanent vocalist, he recorded with Slipknot at Indigo Ranch in Malibu, California and released Slipknot, the band's debut album that peaked number one on the Top Heatseekers chart, went double platinum in the United States, and was included in the 2006 book 1001 Albums You Must Hear Before You Die. Taylor was accused of copyright infringement, regarding the lyrics of the song "Purity", but no action was taken. Taylor began recording for their second studio album, Iowa, in 2001 at Sound City and Sound Image in Van Nuys, Los Angeles. It was released August 28, 2001 and peaked number one on the UK Albums Chart, as well as number three on the Billboard 200. While writing Vol. 3: (The Subliminal Verses), Taylor decided to write lyrics that would not warrant an explicit label. It peaked number two on the Billboard 200. All Hope Is Gone was the first Slipknot album to peak number one on the Billboard 200.
