Emraan, who has also been part of the second and the third installments of the franchise, seems gung-ho about shooting for another sequel.
"'Azhar' almost done! Next one...'Raaz 4 Reboot' in nail biting -15 degrees in Transylvania. Off to Draculas castle," the 36-year-old actor posted on Twitter.
The film will be directed by Vikram Bhatt and is slated to hit the screens next year.
Meanwhile, Emraan will be seen in the upcoming movie 'Azhar', a biopic on former Indian cricket captain Mohammad Azharuddin.
The film will narrate the highs and lows of Azharuddin's life as the captain of the Indian cricket team for most of the 1990s and being tainted by a match-fixing scandal in 2000, and getting banned for life.
Directed by Tony D'Souza, 'Azhar', which is jointly produced by Balaji Motion Pictures and MSM Motion Picture, also stars Lara Dutta and Huma Qureshi in pivotal roles and is slated for a worldwide release on May 13 next year.
