Naya Daur (English: New Race) is a 1957 Indian drama film starring Dilip Kumar, Vyjayanthimala, Ajit and Jeevan. Originally filmed in black and white, the film was colourized and re-released on 3 August 2007.

The film is set in post-independence India where industrialization is slowly creeping in. The focus is on tongawallahs who earn their living transporting people on tongas (horse carts). Their livelihood is threatened when the son of a rich landlord (Jeevan) begins operating a bus service in the town, which he subsidizes heavily with the sole intention of first driving the tongawallahs out of the town and then making profits.

Dilip Kumar plays one of the tongawallahs who petitions the landlord over this injustice. Jeevan's character proposes a competition to decide which service is the best: The bus or the tonga? It is decided that there will be a race between the vehicles. If the bus wins, the tongawallahs will not complain further. If the tonga wins, the bus service will stop. This competition was a farce from the start since nobody could dream that a horse cart could beat a machine. Kumar, however, accepts the challenge to everybody's surprise. His logic is that they would be driven to starvation if the bus service continues. This race at least gives them an opportunity to try to do something.

Dilip Kumar, born Muhammad Yusuf Khan on 11 December 1922, is an Indian actor and a former Member of Parliament. He is commonly known as "Tragedy King", and is described as "the ultimate method actor" by Satyajit Ray.

Starting his career with Jwar Bhata in 1944, Kumar's career has spanned five decades and over 60 films. He is widely considered to be one of the greatest actors in the history of Hindi cinema. Kumar was the first actor to receive a Filmfare Best Actor Award and holds the record for the most number of Filmfare Awards won for that category with Shahrukh Khan; eight wins. He starred in films of a variety of genres such as the romantic Andaz (1949), the swashbuckling Aan (1952), the dramatic Devdas (1955), the comical Azaad (1955), the historical Mughal-e-Azam (1960) and the social Ganga Jamuna (1961).

In 1976, Kumar took a five-year break from film performances. In 1981, he returned with a character role in the film Kranti and continued his career playing central character roles in films such as Shakti (1982), Karma (1986) and Saudagar (1991). His last film was Qila in 1998. The Government of India honoured him with the Padma Bhushan in 1991 and the Dadasaheb Phalke Award in 1994 for his contributions towards Indian cinema. Dilip Kumar has acted with actress Vyjayanthimala the most, where they both had acted seven films together including the former's home production Gunga Jumna resulting great on-screen chemistry and alleged affair between them.

Asha Bhosle (born September 8, 1933) is an Indian singer. She is best-known as a playback singer in Hindi cinema, although she has a wider repertoire. Bhosle's career started in 1943 and has spanned over six decades. She has done playback singing for over a thousand Bollywood movies.
