Sandeep Pradeep-starrer Eko, by director Dinijith Ayyathan, has been winning some rave reviews across the country.
Many have also been raving about the movie's pretty frames and wondering where it was shot.
Idukki's Uppukunnu, which isn't too touristy, was the central location for Eko.
Its misty climate, mountain ranges and windy ambience can win over visitors.
It is located 30 km from Thodupuzha, and Idukki's dams are also visible from here.
