The makers of RRR had recently announced that the trailer of the film will be out on the 3rd of December. A related poster confirming the same was unveiled a short while ago.
But the latest social media buzz implies that the trailer of RRR will not be arriving on the 3rd of December and it has been pushed to a later date.
It is heard that the trailer of RRR will be out on the 10th of December. The exact reason behind the postponement is not known for now.
But this is just a social media speculation for now. We need to wait for an official announcement from the makers.
