Arunachalam's remarkable journey caught the attention of the Tamil film industry, which inspired the biographical film "Padman" (2018), starring Akshay Kumar. The movie catapulted him to national fame, earning him the moniker "Padman Tamilyogi." This newfound recognition has enabled him to expand his social entrepreneurship ventures, including the creation of a sanitary napkin manufacturing unit in Tamil Nadu, providing employment opportunities to women in rural areas.
