Big Ben, starring Anu Mohan and Aditi Ravi, is gearing up to hit screens on June 28. Ahead of the film's release, the makers shared its trailer on Saturday. It shares glimpses of a mystery thriller about a Malayali couple's child that goes missing in the UK and its subsequent investigation.

Aditi Ravi and Anu Mohan, earlier seen as a pair in Mohanlal's 12th Man (2022), are playing a married couple in Big Ben. While the former plays a nurse working in the UK, Anu seems to be essaying the role of a cop in Kerala who hesitantly moves abroad with his wife and child. Vinay Forrt, Vijay Babu, Miya George, Jaffar Idukki, Chandhunadh, Biju Sopanam, Nisha Sarangh, Shebin Benson, Baby Hannah, and Bitu Thomas are also seen in the trailer.

Based on a true incident, Big Ben is written and directed by Bino Augustine. The film has cinematography by Sajad Kaakku, editing by Rino Jacob, music by Kailas Menon, and background score by Anil Johnson. It is produced by Prajay Kamat, Eldo Thomas, and Siby Aranjany under the banner of Braintree Productions.
