Ajantrik (known internationally as The Unmechanical, The Mechanical Man or The Pathetic Fallacy) is a 1958 Indian Bengali film written and directed by parallel filmmaker Ritwik Ghatak. The film is adapted from a Bengali short story of the same name written by Subodh Ghosh.
A comedy-drama film with science fiction themes, it is one of the earliest Indian films to portray an inanimate object, in this case an automobile, as a character in the story. It achieves this through the use of sounds, recorded during post-production, to emphasize the car's bodily functions and movements. The protagonist Bimal can be seen as an influence on the cynical cab driver Narasingh (played by Soumitra Chatterjee) in Satyajit Ray's Abhijan (1962), which in turn served as a prototype for the character of Travis Bickle (played by Robert De Niro) in Martin Scorsese's Taxi Driver (1976).
The film was considered for a special entry in the Venice Film Festival in 1959.
