Starting from 'Chennai 600028', till 'Biriyani' through even films like 'Saroja' and 'Mankathaa', Venkat Prabhu has been observed to have a very causal and lighthearted way of narrating even the most intense of stories. But now, he declared he wanted to try something different, and roped in Suriya to play the lead for his upcoming dream 'Masss'. Initial talks about the movie suggested that it might be titled 'Poochandi', until official confirmation from the director himself. Work on 'Masss' started in July this year; but even now, only very little information is available on the movie, because Venkat Prabhu wants this to be a thriller that is filled with suspense. On that regard, we know that one look of the lead's will sport long hair, while the second of his dual roles is a complete suspense. It is jointly produced by Studio Green and Suriya's venture, 2D Productions.

Nayanthara and Pranita play female leads. Poster of 'Masss' was released on Diwali, with Suriya's face carrying an intense expression. The film has Venkat Prabhu's standard crew of Yuvan Shankar Raja on music and Praveen on editing. As for Yuvan, he has revealed that his work on the film is very different from what he has done previously; in fact, there is a song in a movie that's a tribute for Michael Jackson. The composer has reportedly used very different sounds for the film's album. However, Venkat has replaced his standard cinematographer Sakthi Saravanan with RD Rajasekhar. Dialogues for the film are penned down by lyricist Madhan Karky.

Jayaram and Parthiepan play prominent roles in the thriller. Later, Vidhyullekha Raman, Premgi Amaran and Samuthirakani also confirmed their presence in the movie. Actors Karunas, Sriman and Daniel Annie Pope (of 'Idharkuthaane Aasaipattai Balakumara) confirmed their presence in tge movie as spirits. In all, 'Masss' is an experience new not only to Venkat Prabhu, but also to audience, on the grounds of being a supernatural thriller.
