Earlier about a decade ago a novel of Yandamoori Veerendranath was adopted to screen as 'Tulasi Dalam', a thriller that became a sensational hit and later it was 'Kashmora' on celluloid. Vamsi's 'Anveshana' was another successful thriller movie of those contemporary times.

Later, many suspense thrillers were made, but did not make a mark. After a hiatus, Shekhar Suri's 'A Film by Aravind' registered a major hit.

It is observed in Tollywood that when a subject or genre of film records success, the next films follow the suite. Thus, films like 'Manthra', 'Three' and 'Raksha' followed the thread line. Two of them have succeeded commercially, that led to the generation of thrillers like 'Indumathi and 'Kshudra'.

The latest in the list is 'Dairy' with Shivaji as the hero, which was launched recently. Along with this some more suspense thrillers are in the pre-production stage. All these buzzes depicts that Tollywood is caught highly on a Thriller fever. Now makers are on a thriller spree until the audience gets fed up with it.
