Production and release

After the success of Bommai (1964), Sundaram Balachander made Nadu Iravil the same year. It was based on the 1939 novel And Then There Were None (also known as Ten Little Niggers) by the British writer Agatha Christie. Though he completed the film in 1964-1965, no distributor was willing to buy the film, forcing Balachander to finance and distribute the film himself; Nadu Iravil was eventually released in 1970 and became a major success, prompting several distributors who earlier rejected the film, to return and beg Balachander for distributing it.^[3]
