The first trailer of Sanal Kumar Sasidharan's A'HR (Kayattam) has landed, and judging by the footage, it is unlike anything the filmmaker has done before. AR Rahman shared the trailer on his social media handles.

Touted as an adventure film, Kayattam seemingly carries thriller elements that hint at a mystery factor to the character played by Manju Warrier, who is also turning producer for the first time with the film which has Shaji Mathew and Aruna Mathew as co-producers.

Kayattam is a follow-up to Sanal Kumar's Chola and tracks a group of characters trekking through the Himalayas. Sanal has not only written the script but also edited it and designed the sound. Chandru Selvaraj has handled the camera.
