The Sound of Music is a 1965 American musical film directed by Robert Wise and starring Julie Andrews and Christopher Plummer. The film is based on the Broadway musical The Sound of Music, with songs written by Richard Rodgers and Oscar Hammerstein II, the musical book written by the writing team of Howard Lindsay and Russel Crouse, and the screenplay written by Ernest Lehman. Based on the book The Story of the Trapp Family Singers by Maria von Trapp, the film is about a young woman who leaves an Austrian convent to become a governess to the seven children of a naval officer widower. The Sound of Music contains several popular songs, including "Edelweiss", "My Favorite Things", "Climb Ev'ry Mountain", "Do-Re-Mi", "Sixteen Going on Seventeen", "The Lonely Goatherd", and the title song, "The Sound of Music".
The Sound of Music was filmed on location in Salzburg, Austria; the state of Bavaria in Germany; and at the 20th Century Fox studios in California, USA. It was photographed in 70mm Todd-AO format by Ted D. McCord. The film won a total of five Academy Awards including Best Picture and displaced Gone with the Wind as the highest-grossing film of all-time. The cast album was also nominated for a Grammy Award for Album of the Year.
In a high mountain pasture above Salzburg, Austria, a young woman named Maria (Julie Andrews) finds musical inspiration in the stunning beauty of the surrounding Alps ("The Sound of Music"). Living as a postulant at Nonnberg Abbey, Maria is constantly getting into mischief to the consternation of the nuns and the Mother Abbess ("Maria"). After receiving a request from a widowed Austrian naval captain for a governess for his seven children, Mother Abbess asks Maria to accept the position, and Maria reluctantly agrees ("I Have Confidence").
When she arrives at the von Trapp estate, Maria discovers that Captain Georg von Trapp (Christopher Plummer) keeps it in strict shipshape order, uses a whistle to summon his children, issues orders, and dresses his children in sailor-suit uniforms. Although initially hostile toward her—as with their previous governesses—the children warm to her when she comforts them during a thunderstorm ("My Favorite Things"). The oldest child, Liesl (Charmian Carr), who is "Sixteen Going on Seventeen", sneaks into Maria's window after a secret rendezvous with a messenger boy, Rolfe (Daniel Truhitte). At first she is adamant that she "doesn't need a governess", but Maria offers to be her friend, and she acquiesces. In the coming days, Maria teaches the children how to sing ("Do-Re-Mi") and to play, making playclothes for them from the old drapes in her room.
Meanwhile, the Captain welcomes a visit from a lady friend, Baroness Elsa Schroeder (Eleanor Parker), a wealthy socialite from Vienna, and a mutual family friend Max Detweiler (Richard Haydn), who is intent on finding a novel musical act for the upcoming Salzburg Festival. The Captain is not pleased to learn that Maria has been taking the children on picnics and bicycle rides, climbed trees, and going on boat rides on the lake at the estate. After watching the boat capsize upon its return—throwing Maria and the children into the water in the clothes made from old curtains—he confronts Maria in anger. When she begs him to pay attention to the children and love them, he furiously orders her to return to the abbey.
When the Captain hears the children singing "The Sound of Music" for the Baroness, he apologizes to Maria and begs her to stay—grateful that she's brought music back into his home. Maria agrees, and soon she and the children perform a puppet show ("The Lonely Goatherd") at the house. When Max announces that he has entered the children in the Salzburg Festival, the Captain forbids their participation. Maria and the children encourage him to sing a song, knowing he used to sing and play guitar. With his loving family listening, the Captain sings "Edelweiss".
Some time later, the Captain organizes a banquet in honor of Baroness Schroeder. As eleven-year-old Kurt (Duane Chase) watches the guests dancing the Laendler, he asks Maria to teach him the steps. When he sees Maria dancing in the moonlight, the Captain cuts in and partners her in a graceful performance, culminating in a close embrace. Maria breaks away and blushes, confused about her feelings. Later, the children perform "So Long, Farewell" to say goodnight to the guests. Afterwards, the Baroness, jealous of Maria, convinces her to return to the abbey.
Back at the abbey, Maria keeps herself in seclusion until Mother Abbess gently confronts her, urging her to "Climb Ev'ry Mountain" in search of God's will for her. Maria returns to the von Trapp family. When she discovers that the Captain is now engaged to the Baroness, she agrees to stay until they find a replacement governess. Soon, the Captain breaks off the engagement, realizing that he is in love with Maria. At the gazebo, they declare their love for each other, and the two share a romantic kiss ("Something Good"). Soon after, the two are married in an elaborate ceremony in the cloister church at Mondsee, with many of Austria's elite, as well as the nuns from Nonnberg Abbey, in attendance ("Maria (reprise)").
While the Captain and Maria are on their honeymoon in Paris, Max enters the children in the Salzburg Music Festival against their father's wishes. Austria has also been annexed into the Third Reich in the Anschluss. When they return, the Captain is informed by telegram that he must report as soon as possible to the German Naval Headquarters in Bremerhaven to accept a commission in the German Navy. Strongly opposed to Nazism, the Captain tells his family they must leave Austria.
As the von Trapp family attempts to leave during the night, they are stopped by Nazi guards outside their estate. They tell the guards that they must perform that night in the Salzburg Festival. Hans Zeller (Ben Wright), the recently appointed Nazi Gauleiter, agrees to accompany them to the hall, but insists that the Captain depart for Germany immediately after the performance. Later that night, during their final number, "So Long, Farewell", the family escapes with help from Max.
The von Trapp family seeks shelter from the patrolling guards at the abbey cemetery, but are soon discovered by Rolfe—now a proud Nazi—who threatens to shoot the Captain. The Captain is able to disarm the boy, who then calls for help. After the family escapes in a waiting car, the Nazis try to pursue, but their cars will not start—the nuns having removed the spark plug wires and ignition coils. The next morning, the von Trapp family are hiking over the Alps into Switzerland and freedom ("Climb Ev'ry Mountain").

- Heather Menzies as Louisa von Trapp, the third child, thirteen. She and Brigitta are often together, and she is a bit of a daydreamer.
