Allu Arjun and Atlee are collaborating on the massive Rs 1000 crore sci-fi film Raaka. The movie will reportedly span two distinct time periods, a tribal past and the present. Deepika Padukone will feature in the historical segment, while Murnal Thakur appears in modern scenes. Shah Rukh Khan is slated for a special cameo, which is yet to be filmed overseas.
