The Croods is a 2013 American 3D computer-animated adventure comedy film produced by DreamWorks Animation and distributed by 20th Century Fox. It stars the voices of Nicolas Cage, Emma Stone, Ryan Reynolds, Catherine Keener, Clark Duke, and Cloris Leachman. The film is set in a fictional prehistoric Pliocene era known as "The Croodaceous" (a prehistoric period which contains fictional prehistoric creatures) when a caveman's position as a "Leader of the Hunt" is threatened by the arrival of a prehistoric genius who comes up with revolutionary new inventions as they trek through a dangerous but exotic land in search of a new home.

The Croods was written and directed by Kirk DeMicco and Chris Sanders, and produced by Kristine Belson and Jane Hartwell. The film premiered at the 63rd Berlin International Film Festival on February 15, 2013, and was released in the United States on March 22, 2013. As part of the distribution deal, this is the first film from DreamWorks Animation to be distributed by 20th Century Fox, since the end of their distribution deal with Paramount Pictures.

The Croods received generally positive reviews, and proved to be a box office success, earning more than $587 million on a budget of $135 million. The film launched a new franchise, with a television series, Dawn of the Croods, which debuted on December 24, 2015, on Netflix. A sequel was announced for a 2018 release, but was later cancelled.
Nicolas Cage as Grug Crood, a caveman who is the well-meaning but overprotective and old-fashioned patriarch of the Croods family.
Emma Stone as Eep Crood, a rebellious teenage cavegirl who is Grug and Ugga's eldest daughter and is filled with curiosity and a desire for exploring and wonder.
Ryan Reynolds as Guy, a nomadic boy who is not as strong as the Croods, but prefers using his brain and comes up with various ideas and inventions. He is accompanied by a sloth named Belt.
Catherine Keener as Ugga Crood, a cavewoman who is Grug's wife, the daughter of Gran, and the mother of Eep, Thunk, and Sandy. She is more open-minded than Grug, but also finds it difficult to keep her family safe.

The film was announced in 2005 under the working title Crood Awakening, originally a stop motion film being made by Aardman Animations as a part of a "five film deal" with DreamWorks Animation. John Cleese and Kirk DeMicco had been working together on a feature based on Roald Dahl's story The Twits, a project that never went into production. DreamWorks got a copy of their script and liked it, and invited Cleese and DeMicco over to take a look at the company's ideas to see if they found something they would like to work with. They chose a basic story idea about two cavemen on the run, an inventor and a luddite, and wrote the first few drafts of the script. In January 2007, with the departure of Aardman, the rights for the film reverted to DreamWorks.

In March 2007, Chris Sanders, the writer of Mulan and writer/director of Lilo & Stitch, joined DreamWorks to direct the film, with intentions to significantly rewrite the script. In September 2008, it was reported that Sanders took over How to Train Your Dragon putting The Croods on hold, and thus postponing its original schedule for a year to a then planned March 2012. The film's final title, The Croods, was revealed in May 2009, along with new co-director, Kirk DeMicco. In March 2011, the film got another delay, being pushed back a year to March 1, 2013, and finally settled at March 22.
Full movie was released on DVD and Blu-ray
