Veteran actor Mic Mohan has been roped in for a prominent role, rumored to be the lead antagonist, but no official confirmation is given yet.
Mic Mohan returned to cinema after a seven-year break with the film Haraa, directed by Vijay Sri G.
The movie, Thalapathy68, is the first collaboration between Vijay and Prabhu.
Vijay will allegedly play a dual role in the movie, made possible with the use of de-aging technology, but official confirmation is awaited.
The film started shooting in early October and the crew has relocated to South Africa for an action sequence. The film's music is by Yuvan Shankar Raja.
