That which moves is called a car[a]) is a 1 January 1958 Indian musical comedy film directed by Satyen Bose.

[2] Expected by Kishore Kumar to flop,[3] Chalti Ka Naam Gaadi opened to major commercial success, eventually becoming the most successful work of Bose and Ganguly brothers,[1] as well as Madhubala's fourth consecutive major hit of 1958, thus solidifying her position as the top female star of the late 1950s and early 1960s.

[4] Chalti Ka Naam Gaadi has received overwhelmingly positive reviews from critics for its comical situations, soundtrack, execution, and performances.

One day, while Manmohan is on the night shift, a woman named Renu comes to the garage seeking help as her car breaks down.

After Jagmohan takes off (not before drinking 10 glasses of water due to anxiety), Renu decides to call Manmohan.

On the sets of Chalti Ka Naam Gaadi, Madhubala rekindled a friendship with Kishore Kumar, her childhood playmate, and friend Ruma Guha Thakurta's ex-husband.

To his disgust, the film became a success; as he did not want to add to his earnings, he gave Chalti Ka Naam Gaadi and all its rights to his secretary Anoop Sharma, who retained the copyright.

[16] Chalti Ka Naam Gaadi has received overwhelmingly positive reviews from modern-day critics.

Author Dinesh Raheja, writing for Rediff.com, said that "if the best screwball comedies are those that continue to connect even with the modern generation, this fifties jest-setter is the sure shot winner.

"[5] He also commented favorably on Madhubala and Kishore Kumar's chemistry, adding that Chalti Ka Naam Gaadi was the finest of the five films they made together.

[5] Sandipan Deb of Mint called it "best Hindi movie ever made", noting its treatment of female characters:[2] What is not often mentioned about Chalti Ka Naam Gaadi is its portrayal of women.

Madhubala's character is that of a remarkably liberated woman, driving her car and determined to be in charge of her life in a male-dominated world.
