Naga Chaitanya, Vijay Sethupathi and Dulquer Salmaan launch Don't Sleep teaser

Naga Chaitanya, Vijay Sethupathi and Dulquer Salmaan have unveiled the teaser of Don't Sleep, a psychological thriller with Indhra Raam in the lead.

The film is the Telugu directorial debut of noted cinematographer Shamdat Sainudeen. V Chudamani produces it under the V Dream Films banner.

Sleep itself is the danger here. Every time the hero closes his eyes, the figure hunting him moves closer. His dreams start spilling into his waking life, and staying alive comes down to staying awake.

Ravindra Vijay plays the menacing antagonist who pursues him. Indhra Raam plays the hunted man as fragile and exposed, which gives the threat more weight.

Shamdat's years behind the camera show in the teaser's frames, which set an eerie, uneasy mood from the first shot. Gokul Harshan's background score keeps the tension tight, so the danger never feels far away.
