Prakash Raj narrated the concept of Gaganam during the release time of Aakasamantha to
Dil Raju. The producer loved it and planned to produce it in Telugu while Prakash does it in Tamil with in a combined budget of 5 crores.
Later, Dil Raju had shown the preview of Tamil original of Aakasamantha to Nagarjuna and the actor loved the film. But when Dil Raju asked Nag whether he could act in Prakash Raj’s role so that I could remake Akasamantha in Telugu, Nagarjuna said that it won’t suit his image at that point of time and hence turned down the offer.
