Motor Sundaram Pillai is a 1966 Indian Tamil-language drama film directed by S. S. Balan and written by Veppathur Kittoo.

Motor Sundaram Pillai is the directorial debut of Balan, whose father Vasan produced the film under Gemini Studios.

The 1959 American film The Remarkable Mr. Pennypacker, adapted from a play written by Liam O'Brien, which was inspired by a real life incident, was a global success, especially in Madras (now Chennai).

Veppatthur Kittu of Gemini Studios wrote a screenplay based on this film (with changes made to suit regional tastes) and approached Sivaji Ganesan to act.
