The film was brought to life by a team of notable talents from the Bengali film industry. The entire project was steered by its director, Bratya Basu, a man of many hats—a professor, dramatist, actor, and politician. Basu’s background in theater is evident in Teesta ’s character-driven narrative and intimate, almost stage-like exploration of emotional conflict. He has described the film as being about "a woman who falls in love with a younger man and how the experience turns nasty," capturing the essence of its devastating central relationship.
