There had been rumours for long about Ranveer, 30, and Rohit collaborating on a project.
26-year-old Tamannaah, whose last film "Baahubali: The Beginning" was a huge success, joins in this high octane, thrilling project.
"Ranveer's energy, exuberance and huge popularity make this project more interesting, and Tamannaah is a massive star with South Indian audiences. I really can't be talking about this. But yes, they are on board. Wait and watch, it will be worth the wait," the "Dilwale" director said in a statement here.
