American screenwriter C Robert Cargill, who penned Benedict Cumberbatch starrer film 'Doctor Strange', took to Twitter to praise SS Rajamouli's 'RRR'. "Friends came over last night to initiate me into the cult of RRR...and I'm here to report I'm now fully, truly, deeply a member," Cargill wrote, adding, "This is the craziest, most sincere, weirdest blockbuster I've ever seen."
