Actor Aamir Khan, who has experimented with genres in his movies, says he is scared about not trying something new. The actor will soon be seen in "Thugs Of Hindostan", Yash Raj Films' mega project which features Aamir for the first time with megastar Amitabh Bachchan. They are joined on-screen by Katrina Kaif and Fatima Sana Shaikh in what promises to be a high-octane action drama.
