Yamla Pagla Deewana Phir Se, the third film in the franchise, is an ode to Ayurveda. Yes, you heard that right. Sunny Deol plays vaid Puran Singh who can cure any ailment with an ancient herbal concoction called the 'Vajra Kavach'. Among the three of them, the Deols have over 100 years of making movies. I think it's time to reinvent.
