The Hollywood studio will distribute the two films, to be directed by Kunal Deshmukh and Vikram Bhatt respectively.
"We are hugely excited announcing our alliance with Vishesh Films for two films and we believe that these are partnerships that we are going to value and we are going to build with time.
"Vishesh Films in my judgement is a very unique production house. I admire them for three things. They make concept films, they make films cost-effectively and in budgets and, thirdly, it's all about passion and creativity for them, " Vijay Singh, CEO of Fox Star Studios, told reporters here.
Mahesh Bhatt said: "This is the stuff that dreams are made of. We are very happy with this alliance. It is a moment to celebrate for us."
While "Informer" will star Prachi Desai, Emraan Hashmi and Randeep Hooda, "Raaz 3" will star Jacqueline Fernandez along with Emraan.
