Sukumar is presently busy with two films. While one is Ram Charan's Rangasthalam, another one is Darsakudu, which he is also producing.
But there is one trick that has to be learnt from the director. He knows how to use the stars he casts in his 'commercial films'. We know that he has his own banner for making small films.
So when Kumari 21F happened, he was in the process of making Nannauku Prematho and the entire promotion was done by NTR Jr.
Since the film was a commercial hit, Sukumar got NTR to launch the teaser of Darsakudu this time too as a sentiment.
Meanwhile, he got Rakul Preet Singh to launch a song of Darsakudu. Later, he got Samantha to launch another song.
Finally, he got Ram Charan to launch the entire audio of the film. Incidentally, the audio launch will happen tomorrow.
Since Ram Charan and Samantha are part of Sukumar's Rangasthalam, he got them to their bit for Darsakudu.
So it is for the stars of his film to understand that they will have to do additional promotional work for Sukumar's home banner while signing for his films.
