Chhoti Si Baat is a 1975 Hindi romantic comedy film directed by Basu Chatterjee. The film's title means "Such a Small Thing" in Hindi. Considered one of the best Hindi comedy films of the 1970s, it is a nostalgic favourite for its quirky take on pre-hypercongestion Bombay. The film became a box office hit and also earned Filmfare nominations and a Filmfare Award for Best Screenplay for Basu Chatterjee. It also established Amol Palekar as having an uncommon comic talent for playing mousy characters, a role he would go on to repeat several times in his career. This movie is based on "School for Scoundrels", a 1960 British Comedy which itself was based on the "Gamesmanship" series of books by Stephen Potter.Wikipedia
