The Dalda film was an advertisement created for the marketing campaign in 1939 for a vanaspati (cooking fat) brand called Dalda. It was conceived by Harvey Duncan, of LINTAS Ad agency and created in 1939 by Bombay Talkies. The film was shown from a cinema van that went round remote countrysides showing the film to villagers. This van consisted of a huge round tin to imitate the product packaging. The 1200-ft film is the second known screen motion film based advertisement in India, the first being a 1931 advertisement for a GM Chevrolet.
