Speaking at the pre-release event of 'Rangasthalam', Sukumar was all praise for the film's cast and crew, especially his hero Ram Charan.

He started his speech by hailing Chiranjeevi as a 'position' greater than Chief Minister's.  He then narrated how the Megastar appreciated him after watching Rangasthalam's rushes recently.  "I was so overwhelmed by his appreciation that I felt sorry nobody was there beside me to hear those compliments.  Nobody was there to witness my achievement," Sukumar said.

Suku then described his producers as sensitive to the needs of their cast and crew.  About DSP, he said, "I get emotional whenever I talk about Devi.  When he is around, a film doesn't even need a story.  He gave the output in a very short time of 4.5 days.  As for Chandrabose garu, his lyrics for the movie are the zenith of his poetry."

About Samantha, Sukumar said that he wants to be her life-long director just as Naga Chaitanya is her life-long partner.  "I want to cast her in a 40-year-old character when she is 40, so on and so forth," he said.

He praised art director Ramakrishna's work as realistic.  "I am afraid nobody is going to believe it's a set," he remarked.  

About others, he said, "It was very difficult to show Anasuya as an Atthamma.  Nobody can show her as an aged woman.  As for Aadhi Pinisetty, he got into the skin of her character from day one.  It didn't even occur to me that I was not interacting with him.  I didn't feel the need as he was spot-on.  Ram-Lakshman duo's fights are so pure that they bring out the emotions as they are.  Sushmitha went shopping in Polavaram for her brother's sake.  Imagine Chiranjeevi garu's daughter doing it!"

About Ram Charan, Sukumar noted, "On the very first day of the shoot, everybody clapped as soon as he was done with the first shot.  I usually am scared when people clap.  It's because you then can't ask for another take.  With Ram Charan, I didn't have to worry about retakes.  The first day of the shoot was done spontaneously.  The 'Nannu antha sound engineer antaru' dialogue was shot.  I too started clapping after he completed the shot.  Someone as difficult to be convinced as Prakash Raj garu also clapped.  Charan has shown every emotion in its purest form.  It must be because he is a pure person.  The best performance is that performance after watching which you shouldn't think of any other hero."
