The Wiggles are an Australian children's music group formed in Sydney, New South Wales, in 1991. The current members of the group are Anthony Field, Lachlan Gillespie, Simon Pryce, and Emma Watkins. The original members were Field, Phillip Wilcher, Murray Cook, Greg Page, and Jeff Fatt. Wilcher left the group after their first album.
The Wiggles enjoyed "almost universal approval" throughout their history. Their songs were sung and played in pre-schools all around the world. Between 2000 and 2010, The Wiggles earned 21 Gold records. According to a 2012 news release published to announce the retirement of Cook, Fatt, and Page, they earned several Platinum, Double Platinum and Multi-Platinum records, as well as sold 23 million DVDs and 7 million CDs. They performed, on average, to one million people per year. After 2003, front-row tickets to their sold-out concerts in the US were scalped for US$500. The group responded by reducing the number of seats sold per transaction, in order to keep prices down and avoid further tickets scalping. In 2008, the group found themselves in the midst of what The Daily Telegraph called a "ticketing scandal"; scalpers tried to sell a A$19 ticket on eBay for almost A$2,000 and a set of three tickets for A$315 for concerts in Melbourne, and a group of three tickets to a Wiggles UNICEF charity concert in Sydney had a price tag of A$510. The tickets were taken off eBay and voided. In what Paul Field called "one of the highlights of their 15 years of being together", The Wiggles were awarded an honorary doctorate degree from Australian Catholic University in 2006. Cook gave an address during the private ceremony honouring them. They were awarded another honorary doctoral degree in 2009 from their alma mater, Macquarie University. The group was named UNICEF goodwill ambassadors in 2008; they held a special concert to raise money for the organisation. In 2010, the four original members of The Wiggles were appointed Members in the Order of Australia for their service to the arts in Australia, especially children's entertainment, and for their contributions and support of several charities. They called the honour their "biggest recognition yet". The group has always invited children with special needs and their families to pre-concert "meet and greet" sessions. According to Fatt, many parents of these children have reported that The Wiggles' music has enhanced their lives, and that children with autism "respond to [The] Wiggles and nothing else". The Wiggles, throughout their history, have visited and performed for patients at the Sydney Children's Hospital every Christmas morning. In 2011, ABC Music released an album titled Rewiggled: A Tribute to The Wiggles" to celebrate the group's 20th anniversary. The album features covers of many favourite Wiggles songs performed by notable Australian music artists.

Orci was born in Mexico City on July 20, 1973, to a Mexican father and a Cuban mother. His mother immigrated to the United States with her parents after Fidel Castro came to power. Orci grew up in Mexico, and moved with his family to the United States at the age of 10. He was raised in Texas, Los Angeles and Canada.
In April 2014, Orci and Kurtzman confirmed to Variety that they are no longer going to work together on film projects but will still collaborate on television. Kurtzman wanted to work on the Spider-Man film franchise, while Orci was linked to the directorial role for Star Trek 3. Orci confirmed later that year in July that he was not involved in the production of The Amazing Spider-Man 3 alongside Kurtzman. Orci and Kurtzman's K/O Paper Products continues to operate as a production company within CBS Television Studios, and has created the series Scorpion inspired by the life of Walter O'Brien for the 2014-15 season and Limitless was created for the 2015-16 season from the 2011 film. Prior to the split of Kurtzman and Orci, the duo were lined up to write the third film in the new Star Trek series. In May 2014, Skydance and Paramount Pictures announced that Orci was to direct the third installment of the Star Trek reboot franchise, after Abrams moved on to direct Star Wars: The Force Awakens. This would have marked Orci's directorial debut, and he was to write the script alongside co-writers JD Payne and Patrick McKay. Due to his commitment to Star Trek 3, he dropped out of a new Power Rangers film, for which he would have been executive producer. But on December 5, it was announced he would no longer be directing the Star Trek film. He remains credited as a producer on the film, and was replaced by Doug Jung and cast member Simon Pegg as the script writers after Orci's initial script was dropped. Orci was replaced as director by Justin Lin, who had previously directed films in The Fast and the Furious franchise. Orci created Matador with the idea that the main character would be a "soccer player by day who is a spy by night", and called him a "Latin James Bond". The series was broadcast on the El Rey Network created by Robert Rodriguez. It was renewed for a second season shortly before the pilot was broadcast, which had been directed by Rodriguez. But following the production of the first season, the series was cancelled despite the earlier renewal. This decision was blamed on poor international sales.
