We had earlier reported that Sanal Kumar Sasidharan's follow-up to Chola is titled Kayattam. The film has Manju Warrier involved not only as an actor but also a producer. The makers have released a new poster which gives us a glimpse of Manju in character.

It has been revealed that Sanal and team devised a special language for the film called Ahr Samsa. As the word Ahr translates into the film's Malayalam title, the film's posters feature 'Ahr' beside the title. Kayattam is about a group on a trekking trip through the Himalayas.

The film's unique narrative is told through 10 songs written in the Ahr Samsa language and prepared by Ratheesh Eettillam. All the songs have been shot in an improvised manner on the Himalayan trekking sites featured in the film.

Chandru Selvaraj, who worked under veteran cinematographer Thiru, is making his debut as an independent cinematographer with Kayattam.

Chola art director Dileep Das has worked on Kayattam too, which is a joint venture of Sanal's Niv Art Movies, Manju Warrier Productions, and Parrot Mount Pictures.

Aside from directing the film, Sanal has also written the script in addition to editing it and working on the sound design.
