Context paragraphs:
Cadbury Mr. Big: Mr. Big is the largest sized candy bar produced by Cadbury in Canada, hence the name.  The standard bar is made of a layered vanilla wafer coated in caramel, peanuts and rice crisps covered in a brown simulated chocolate-like coating.  Because of Canada's higher chocolate standards compared to other areas of the world, it is not considered a "chocolate bar" and is labeled instead as a "candy bar".  The bar is the length of two "standard"-sized bars – around 20 centimeters (8 inches) long.  Additional varieties include Mr. Chew Big, Mr. Big Fudge, and Mr. Big with Maple.

Talkin' 'bout Soul: Talkin' 'bout Soul consisted of tracks recorded by Little Richard for Vee-Jay Records in 1964 and 1965.  All of the songs had been released before except "You Better Stop", thus warranting its inclusion in the album chronology.  "Something Moves In My Heart" had previously been included on the 1971 UK released album, "Mr. Big", under the title "Every Time I Think About You".  This album is essentially the "Mr. Big" album with one extra previously unreleased track.

Bus 174: Bus 174 (Portuguese: Ônibus 174 ) is a Brazilian documentary film released on October 22, 2002.  It is the debut film of director José Padilha and co-director Felipe Lacerda.  In 2000, Sandro do Nascimento, a young man from a poor background, held passengers on a bus hostage for four hours.  The event was caught live on television.  The movie examines the incident and what life is like in the slums and favelas of Rio de Janeiro and how the criminal justice system in Brazil treats the lower classes.  Within the film, Padilha interviews former and current street children, members of the Rio police force, the Rio BOPE police team, family members, and sociologists in order to gain insight into what led Nascimento to carry out the hijacking.

Elite Squad: Elite Squad (Portuguese: Tropa de Elite , ] lit. " "Elite Troop"") is a 2007 Brazilian crime film directed by José Padilha.  The film is a semi-fictional account of the "Batalhão de Operações Policiais Especiais" (BOPE), the Special Police Operations Battalion of the Rio de Janeiro Military Police, analogous to the American SWAT teams.  It is the second feature film and first fiction film of Padilha, who had previously directed the documentary "Bus 174".  The script was written by Bráulio Mantovani ("City of God") and Padilha, based on the book "Elite da Tropa" by sociologist Luiz Eduardo Soares and two former BOPE captains, André Batista and Rodrigo Pimentel.

Big Bigger Biggest: Greatest Hits: Big, Bigger, Biggest!  The Best of Mr. Big is a compilation CD and DVD by the hard rock band Mr. Big.  CD released in 1996 and DVD released in 2009, it contains the following songs:

Mr. Big (film): Mr. Big is a 2007 documentary directed and produced by Tiffany Burns and edited by Alec MacNeill Richardson.  The documentary examines the "Mr. Big" undercover methods used by the Royal Canadian Mounted Police (RCMP).  In these operations, RCMP officers pose as gang criminals and develop a relationship with the target in the hope of eventually determining what, if any, knowledge the target has of the crime being investigated.  "Mr. Big" operations have been credited with securing difficult convictions in a large number of cases, but concerns have been raised that they involve a risk of false confessions and wrongful convictions.

Mr. Big (Little Richard album): Mr. Big, released in the middle of his Reprise Records period, was another compilation of Little Richard's mid 1960s recordings for the Vee Jay Records label.  Released on the UK Joy label, it is included in the album chronology because none of the tracks had previously been released on an album.  A later album with not only the same name, but also the same cover was released for the US market in 1974 with different tracks.  (See "The Alternate Mr. Big").

Sandro Rosa do Nascimento: Sandro Rosa do Nascimento (July 7, 1978 – June 12, 2000) was the perpetrator of the Bus 174 hostage crisis in Jardim Botânico, Rio de Janeiro, Brazil.  Nascimento boarded a public bus, intending to rob the passengers.  However, the incident developed into a hostage situation, which was broadcast live by most Brazilian national television channels.

Mr. Big (Mr. Big album): Mr. Big is the self-titled debut album by the American hard rock supergroup Mr. Big.  Produced by Kevin Elson and Val Garay, the album proved a partial commercial success, reaching the 46th slot on the Billboard 200 chart.  Lead-off single "Addicted to that Rush", featuring the band's aggressive guitar and bass playing, also brought the group some mainstream attention, reaching the No. 39 slot on the Billboard Mainstream Rock chart.  300,000 copies were sold, according to a "Musician" magazine interview with Mr. Big in 1990.

Paul Gilbert: Paul Brandon Gilbert (born November 6, 1966), is an American hard rock/heavy metal guitarist.  He is best known for being the co-founder of the band Mr. Big.  He was also a member of Racer X, with whom he released several albums.  Following Mr. Big's disbandment in 1996, Gilbert launched a solo career, for which he has released numerous solo albums, and featured in numerous collaborations and guest appearances on other musicians' albums.
