In his latest interview, Ram Charan admits that he has signed up to do the RRR movie even though a bound script is not in place.  This he has done as he fully trusts Rajamouli's talent.  

It's safe to assume that NTR too has done much the same as he would be the last one to doubt Jakkanna's knack for mind-blowing output.  The combination of Rajamouli, NTR, and himself has also attracted Cherry to agree to do the film right away.

The Mega Power Star and the Young Tiger must have heard the storyline, though.  For months after 'Baahubali-The Conclusion', Rajamouli kept on asking his father for an exciting storyline.  The father-son duo was hardly ready with a script for all those months.

To be produced by DVV Danayya, the film is expected to go on the floors in August.
