Less than four months after its release, Pixar's "Finding Dory" has surpassed $1 billion at the worldwide box office to become the fifth-highest grossing animated film of all time.

The sequel is the third film -- and third Disney film -- this year to cross that milestone, after "Captain America: Civil War" and "Zootopia," the top-grossing releases of 2016.

The long-awaited follow-up to 2003's "Finding Nemo," "Finding Dory" focuses on the amnesiac blue tang, voiced once again by Ellen DeGeneres, who sets out to reunite with her parents. Along the way she's captured and taken to a public aquarium in California, leaving Marlin and Nemo to try to rescue her.

"Finding Dory" debuted June 17 in North America, where it went on to earn $484.8 million to become the top-grossing film of the year. It received staggered international release through September, which has contributed to its box-office longevity.

The sequel has raked in $516.7 million overseas, with Japan leading the way with $65.9 million, followed by the United Kingdom with $55 million, China with $38.4 million, Australia with $36.2 million and Brazil with $34.5 million.

"Finding Dory" will be available beginning Oct. 25 on digital HD, along of the short film "Piper," ahead of its Nov. 15 release on Blu-ray and DVD.
