Actually, they did not work with each other for every film of the director. For Arya-2, B. Rajasekhar handled camera and for 100% Love, Venkat Prasad handled camera. Nannaku Prematho camera work was handled by Vijay C Chakravarthy.
Ratnavelu-Sukumar duo became a combination that people talk about because of their friendship and work they accomplished in Arya, Jagadam, 1Nenokkadine and Rangasthalam films. Ratnavelu worked for Kumari 21F, first production of Sukumar as well.
Devi Sri Prasad did not miss most of the films in which Sukumar was involved but Ratnavelu was not a permanent fixture. Still, the cinematographer tweeted wishes to his friend's film. He wrote,
"Dear @aryasukku All the best for #AA20 !! Expecting another Cult classic hit like Rangasthalam!! Both of us are gonna miss each other this time. See you in the next movie Best wishes to @alluarjun , @MythriOfficial @ThisIsDSP # kuba Dop ,Monika Ramkrishna !!"
Why did a simple best wishes tweet get such traction to become a trending topic? All thanks to Mahesh fans. Ratnavelu is working as a DOP for Sarileru Neekevvaru and before #AA20 was announced, Sukumar & Mahesh were supposed to work together.
They had creative differences and decided to move on to their next projects. Mahesh should have started Sukumar-Mythri film instead of SLN.
When you look for controversy or behind the curtains drama, even a simple tweet becomes a cryptic message. Fans made the tweet a trending topic, thinking Sukumar distanced his friend as he is working with Mahesh.
Even Devi Sri Prasad is continuously working with Mahesh from last four films, Sukumar did not distance him for #AA20. Ratnavelu might have wanted to work with Sukumar after Rangasthalam but the director might have opted for other cinematographer to finish the work faster in lesser budget as #AA20 could be the first film where Sukumar will be working over a tight deadline after Nannaku Prematho, according to reports.
Hence, did it really need to be a trending topic? We leave it your distinctive judgement as you're better adjudicators.
