We Bought A Zoo was released in the United States on December 21, 2011 by 20th Century Fox.^[3] The film earned $120.1 million on a $50 million budget. We Bought a Zoo was released on DVD and Blu-ray on April 3, 2012 by 20th Century Fox Home Entertainment. Dartmoor Zoological Park (originally Dartmoor Wildlife Park), on which the film is based, is a 33-acre zoological garden located near the village of Sparkwell, Devon, England.

Benjamin Mee has been grieving the loss of his wife, Katherine, for seven months. When his 14-year-old son Dylan is expelled from school, Benjamin realizes that the family's current situation is not working, they are all grieving, and everything around them reminds them of Katherine. Benjamin decides to make a fresh start, starting with a new home.

He tours many homes with his 7-year-old daughter, Rosie, and their realtor, Mr. Stevens, but find none to their liking until Rosie sees a listing for a large old house. Mr. Stevens tries to dissuade them from considering it, but as they tour the grounds, Benjamin declares that "it's perfect". Stevens explains that if they want the house, then they must also buy the zoo on the property which closed several years before. Benjamin, seeing Rosie playing happily with the peacocks, resolves to buy the zoo.

Dylan, frustrated by the idea of moving away from his friends, retreats into his art. Benjamin's accountant brother, Duncan, tries to discourage him from the purchase, but he buys it anyway.

The zoo staff, led by head keeper Kelly Foster, start making renovations to reopen the zoo to the public. When Kelly asks Benjamin why he bought the zoo despite knowing nothing about zoo management, he simply responds, "Why not?" Meanwhile, Dylan is very unhappy and misses his friends, causing him to retreat further into his art. He is soon befriended by Kelly's 13-year-old homeschooled cousin, Lily, who develops a crush on him.

Walter Ferris, a strict USDA inspector, arrives for a surprise visit and makes a list of repairs that would cost over $100,000. Benjamin cannot afford the repairs and gossip spreads that he will probably sell the zoo. The staff's morale sinks, fearing the property will be sold to a buyer that will close it down. Dylan is overjoyed when Lily tells him the rumor about his family leaving, which hurts her feelings.

Benjamin learns that Katherine bequeathed him an investment account with instructions to use the money wisely while listening to his heart. Duncan advises him to walk away and start over with the money, but Benjamin decides to use the money for the repairs.

Dylan, unhappy about having to stay, confronts his father and they have a heated argument. They reconcile the next morning and Dylan admits he misses Lily. Benjamin tells Dylan his favorite motto: that you only need 20 seconds of courage for something great to happen. Benjamin realizes that instead of trying to start over by forgetting his wife, he should accept that she will always be a part of him. Dylan, following his father's advice, confesses his love to Lily, and she forgives him.

Prior to the zoo's grand opening, the facility passes a stringent inspection by Ferris, who grudgingly wishes them good luck. They learn that the worst rainstorm in 100 years may wash out the zoo's grand opening. Fortunately, the weather clears by the morning of the grand opening, but they are disappointed when it appears that no one is visiting.

Dylan discovers that a fallen tree has blocked the access road with a large crowd of visitors waiting behind it. The staff help everyone climb over the tree, and the attendance is so high that they run out of tickets. Benjamin and Kelly set out to find more and end up face to face in a shed, where Kelly admits that she has a crush on Benjamin and they kiss.

Benjamin takes Dylan and Rosie to the restaurant where he met Katherine. He tells them the story of how he worked up the nerve to approach her table with "20 seconds of insane courage." He visualizes her at the table, and asks why such an amazing woman would talk to someone like him. She responds, "Why not?"

The zoo scenes were filmed at Greenfield Ranch in Hidden Valley, Thousand Oaks, California, where a zoo was erected for the filming.^[8][9]

In August 2011, it was announced that Icelandic musician Jón Þór "Jónsi" Birgisson, the lead singer of the band Sigur Rós, would be composing the music scores for We Bought a Zoo.^[11] Director Crowe described the choice as "only natural", since "Jónsi has been a part of the making of We Bought A Zoo from the very beginning".^[11]

The song Gathering Stories was on the shortlist of 39 songs that had a chance of being nominated for Best Original Song Oscar at the 84th Academy Awards.^[12] This song was co-written by Jonsi Birgisson and Cameron Crowe.^[12]

While the official CD release of the movie soundtrack only includes music by Jón Þór "Jónsi" Birgisson and Sigur Rós,^[13] the complete soundtrack of the film included a variety of artists.^[14]

The film's plot and actual events differ. The real Benjamin Mee is British, whereas in the film he is American. The story was adapted for an American audience and Mee approved the changes.^[26] The actual zoo Mee bought is Dartmoor Zoological Park, located in Devon, England.^[27] The fictional zoo in the film is called Rosemoor Wildlife Park and is located in California, US.

In real life, Benjamin's wife, Katherine, died after they had bought the zoo and moved in.^[27] In the film, Benjamin bought the zoo after her death. In real life, Benjamin's father had died and his mother needed to move; the farm cost the same price as his parents' house, and his mother came too.^[28] Benjamin and his family made a specific and informed decision to buy a zoo: in the film, it occurred as a result of finding a house they liked.

Instead of an escaping grizzly bear, as portrayed by the film, it was a jaguar called Sovereign that had escaped.^[27] Benjamin's children were also younger (aged four and six respectively) than the children in the film.^[27]

In the film, the zoo was much easier to buy. In real life, it took almost two years to buy.^[27] Benjamin's first offer to buy the zoo was rejected due to his lack of experience in the zoological world.^[27] Finally, the real zoo opened on Saturday 7 July 2007. The film moved that event to the same date in 2010. This later date fell on a Wednesday, but was identified in the script as the original Saturday.

The longtime gag-feud between Matt Damon and Oscars host Jimmy Kimmel continued at the 89th Academy Awards ceremony, where Kimmel jokingly mocked Damon's performance in the movie.^[29]
