Child abuse is the physical, sexual or emotional mistreatment or neglect of a child or children. In the United States, the Centers for Disease Control and Prevention (CDC) and the Department for Children And Families (DCF) define child maltreatment as any act or series of acts of commission or omission by a parent or other caregiver that results in harm, potential for harm, or threat of harm to a child. Child abuse can occur in a child's home, or in the organizations, schools or communities the child interacts with. There are four major categories of child abuse: neglect, physical abuse, psychological/emotional abuse, and child sexual abuse.

Different jurisdictions have developed their own definitions of what constitutes child abuse for the purposes of removing a child from his/her family and/or prosecuting a criminal charge. According to the Journal of Child Abuse and Neglect, child abuse is "any recent act or failure to act on the part of a parent or caretaker which results in death, serious physical or emotional harm, sexual abuse or exploitation, an act or failure to act which presents an imminent risk of serious harm". A person who feels the need to abuse or neglect a child may be described as a "pedopath".

Hans Florian Zimmer, German pronunciation: [hans ˈfloːʁi̯aːn ˈtsɪmɐ]; (born 12 September 1957) is a German film composer and music producer. He has composed music for over 100 films, including award winning film scores for The Lion King (1994), Crimson Tide (1995), Gladiator (2000), The Last Samurai (2003),The Dark Knight (2008), and Inception (2010).

Zimmer spent the early part of his career in the United Kingdom before moving to the United States. He is the head of the film music division at DreamWorks studios, and works with other composers through the company which he founded, Remote Control Productions.

Zimmer's works are notable for integrating electronic music sounds with traditional orchestral arrangements. He has received four Grammy Awards, two Golden Globes, a Classical BRIT Award, and an Academy Award. He was also named on the list of Top 100 Living Geniuses, published by The Daily Telegraph.

Zimmer was born in Frankfurt am Main, Germany. As a young child, he lived in Königstein-Falkenstein, where he played the piano at home, but had piano lessons only briefly as he disliked the discipline of formal lessons. He moved to London as a teenager, where he attended Hurtwood House school. In an interview with the German television station ZDF in 2006, he commented: "My father died when I was just a child, and I escaped somehow into the music and music has been my best friend."

John Powell (born 18 September 1963) is an English composer, best known for his scores to motion pictures. He has been based in the United States since 1997 and has composed the scores to over fifty feature films. He rose to fame in the late 1990s and 2000s, scoring numerous animated films, in addition to his live-action collaborations with directors Doug Liman and Paul Greengrass. His 2010 score for the film How to Train Your Dragon earned him his first Academy Award nomination at the 83rd Academy Awards. He was a member of Hans Zimmer's music studio, Remote Control Productions, and collaborated frequently with other composers from the studio, including Harry Gregson-Williams and Zimmer himself.

Powell was born in London. He originally trained as a violinist as a child, before studying at London's Trinity College of Music. He later ventured into jazz and rock music, playing in a soul band the Fabulistics. On leaving college, he composed music for commercials, which led to a job as an assistant to the composer Patrick Doyle on several film productions, including Much Ado About Nothing.
