The makers of Unni Mukundan's Marco, directed by Haneef Adeni, have announced that the film's teaser will be released on October 13. It is a spinoff of the Nivin Pauly-starrer Mikhael (2018), also helmed by Haneef Adeni.

Besides Unni, Marco features an ensemble cast that includes Kabir Duhan Singh, Anson Paul, Arjun Nandakumar, Durva Thaker, Yukti Tareja, Abhimanyu Shammy Thilakan, Ishan Shoukath, Siddique, Jagadish, and Riyaz Khan, among others. On the technical side, it has cinematographer Chandru Selvaraj, editor Shameer Muhammed, and music director Ravi Basrur, known for his work in the blockbuster Kannada franchise KGF.

In Mikhael, Nivin portrayed the titular character, with Unni taking on the role of the antagonist, Marco Jr. Reports indicate that the forthcoming film will explore Marco's backstory and his descent into the criminal underworld. The makers have described Marco as the most violent film ever produced in Malayalam cinema. The project is bankrolled by Cubes Entertainments in collaboration with Unni Mukundan's own production company, Unni Mukundan Films.

Meanwhile, Unni Mukundan is awaiting the release of Get-Set Baby, a comedy-drama directed by Vinay Govind, where he stars alongside Nikhila Vimal. His upcoming projects also include the long-delayed film Mindiyum Paranjum and Gandharva Jr.
