Haiwaan marks the reunion of Akshay and Saif after 17 years, after the 2008 film Tashan. The upcoming movie is reportedly a remake of one of Priyadarshan’s own Malayalam hits, Oppam, in which Mohanlal played a blind man. In the Hindi version, Saif is to reprise that role, while Akshay will step into the shoes of the main antagonist, originally portrayed by Samuthirakani.
