According to the leaked videos, it appears that the film's creators constructed a set in Saradhi Studios that resembles a hamlet set from movies like Khaleja. Despite the fact that there is no access for anyone to Saradhi Studios to record videos of the set, the creators did not realise that the set is clearly visible from Ameerpet Metro Station, which is close to the studio. Anyone using the metro can now see this set clearly, and they are filming movies of it.
Fans are also concerned that if these films keep appearing in this manner, the hype surrounding that specific set won't be as strong. For instance, the makers of Waltair Veerayya released the Boss party song first before releasing the set and exposing it to the public, which caused a lot of buzz to develop around it. But if the #SSMB28 set is revealed in this way, that wow factor will be gone by the end. We must wait and see what the creators decide.
