The makers of Maamannan have announced that the first look of the film will be out on May 1. The announcement was made along with a teaser poster that shows shadows of Udhayanidhi and Vadievlu overlapping each other. The former is wearing a suit and the latter is clad in veshti. 

Maamannan, produced by Udhayanidhi Stalin's production house, Red Giant Movies, has music by AR Rahman and cinematography by Theni Eswar. It may be noted that Vadivelu, who has been very doing very few films of late, made a full-fledged comeback with Suraj's Naai Sekar Returns. Apart from Maamannan, the actor has Chandramukhi 2 in the pipeline. Meanwhile, Udhayanidhi earlier revealed that Maamannan will be the last project in his cinema career. 

Maamannan will last in the news when Vadivelu was working on the dubbing portions of the film.
