Hrithik Roshan is on a promotional spree even post the release of Krrish 3. It is evident that Hrithik Roshan is leaving no stones unturned to make the third installment of his sci-fi, a great success. From Krrish 3 merchandise and jewellery line to Krrish 3 game for mobile phones to Krrish 3 donuts, Duggu seems to have gone way too far with the promotions of his film.
