• 2008–09: Breakout, transitions and film career launch
After the end of the Best of Both Worlds Tour in January 2008, Walt Disney Pictures released Hannah Montana & Miley Cyrus: Best of Both Worlds Concert, a 3D concert film of the tour, on February 1, 2008, for what was expected to be a one-week run. The film earned over $31 million at the box-office and an average of $42,000 per theater, twice the expected total, convincing Disney executives to extend the release for an indefinite run. "We don't want to turn away kids from the theaters who couldn't get into the concerts," said Chuck Viane, Disney's chief of distribution. The film's soundtrack was released by Walt Disney Records/Hollywood Records on March 11, 2008, and peaked at number three on the Billboard 200.
On July 22, 2008, Cyrus released her second studio album under her own name, titled Breakout. Cyrus said Breakout was inspired by "what's been going on in my life in the past year." Cyrus co-wrote eight out of twelve songs on the album. "Songwriting is what I really want to do with my life forever, I just hope this record showcases that, more than anything, I'm a writer." The album debuted at #1 on the U.S. Billboard 200 chart and its lead single, "7 Things", peaked at number 9 on the Billboard Hot 100. She hosted the 2008 CMT Music Awards with her father in April and the 2008 Teen Choice Awards by herself in August. Cyrus provided the voice of Penny in the 2008 computer-animated film Bolt, which was released on November 21, 2008, to critical acclaim. Cyrus also co-wrote and recorded the song "I Thought I Lost You" as a duet with John Travolta for the film, for which she received a Golden Globe nomination. In September 2009, she participated in the charity single "Just Stand Up!" in support of the anti-cancer campaign Stand Up to Cancer and in the City of Hope Benefit Concert in support of cancer research and training programs. She also became involved in Disney's Friends for Change, an environmentalist group, for which she recorded the charity single "Send It On" along with several other Disney Channel stars.
Cyrus had already begun transitioning to a more grown-up image in late 2008, when her representatives negotiated a deal for novelist Nicholas Sparks to write the screenplay and novel basis for a film that would serve as a star vehicle for Cyrus by introducing her to audiences older than the young fans she had gained through Hannah Montana. Sparks and co-writer Jeff Van Wie developed The Last Song. It was important to Cyrus that she not be type cast as a singer: "I didn't want to be a singer in another film. I don't want to do that anymore. You have no idea how many musicals show up on my door. I want to do something a little more serious." In March 2009, Cyrus published Miles to Go, a memoir co-written by Hilary Liftin chronicling her life through age sixteen. Cyrus starred as Miley Stewart/Hannah Montana in Hannah Montana: The Movie, released April 10, 2009. Both the film and its soundtrack, which contained twelve songs performed by Cyrus, achieved commercial success. The soundtrack's lead single, "The Climb", became a Top 40 hit in twelve countries and introduced Cyrus to listeners outside her typical teen pop audience. Cyrus had considered ending Hannah Montana after its third season, which finished production on June 5, 2009, but Disney retained and exercised its option for a fourth season.
