Ethir Neechal (2013)

What`s in a name? A lot, especially if it is lovingly bestowed on you by your parents. The protagonist was named Kunjithapatham by his parents, after their favourite deity. The weird sounding name makes him the butt of jokes by his classmates in school, college and finally at work. No girl wants to marry him with such a bizzare name! After suffering through a lifetime of bullying and mocking taunts from peers, he's at his wits end. On the advice of his best friend Peter, he meets an astrologer who specialises in giving fancy names. Through the study of numerology, the astrologer believes he can bring about change in fortune by an appropriate change of name! Kunjithapatham now becomes modern and stylish with a new name, Harish and his luck changes. Harish meets Geeta, a school teacher and falls in love with her. But soon, Geeta finds out that Harish is not his real name and he lacks self confidence. She motivates him, and encourages him to stand up for himself saying that there is nothing in a name and it is self confidence that matters in life. In a desperate and intensely sincere attempt to prove to himself, he decides to join the Chennai Marathon, and coaches under Valli, a former national athlete.
