Nowadays dacoit films are not being made. This does not mean that dacoits have disappeared. They are very much there but they are not living in Chambal any more. Today's dacoits do not sit on top of a horse with a gun wearing the costume, black tilak marked on the forehead which we are familiar with.
In the '60s, '70s and '80s, this was one genre that guaranteed and spelt sure shot success. On my research, it was found that K L Saigal played the role of a dacoit in 1934 film Daku Mansoor.
The significant dacoit film of this decade was Paan Singh Tomar released in 2012, a biopic had Irrfan Khan in the role of the bandit who was finally killed in a police encounter in 1981. Here are a few dacoits films that are worth mentioning.
